4 Best Glass Butt Plugs

The benefits of using glass butt plugs over those made from other materials are plenty. Features like cleanability, a more weighty presence, and aesthetics keep me coming back to them. But which of the many products should I buy?

After testing dozens of products, we decided that Crystal Delights Pony Tail Plug was the highest-rated glass butt plug and what we recommend to all our friends and readers. Everything, from the beautiful glass body to the long, glossy tail, which offered a mix of visual and aesthetic appeal, made it stand out. In addition, the team highlighted the premium borosilicate glass, describing it as beautiful and durable.

How We Picked The Products

When testing butt plugs, especially those made from glass, my team and I use a more rigorous testing process than usual. Ensuring that the products we recommend are as comfortable as possible and guaranteed to be safe to use is of high priority.

After distributing the products to my team, I provided them with the following test criteria that we could measure on a scale from 0 to 100. These are the following:

• Flared base: A flared base is a must-have for all anal toys, preventing them from getting stuck in the anal cavity. In this review, we looked for toys with different base designs to satisfy folks looking for eye-catching pieces and those who love extended play.
• Design: When it comes to sex toys you’re planning on putting in your butt, design is everything. Our panel was looking for designs that maximized comfort while simultaneously providing that filling sensation that butt plugs are known for.
• Stimulations: The weighty, rigid feel of glass butt plugs is something that wearers grow to love. We sought products that satisfied the senses and even managed to track down a few with added features like a tail or vibrations.
• Build Quality: Sex toys made from glass aren’t something you want to skimp on. By buying a high-quality toy, you will ensure that the product has what it takes to stand the test of time and will guarantee your safety.
• Value: Unlike other styles of butt plugs, the value of glass can be derived from sensation, unique features like vibrations, or simply the beauty of the plug itself.
• Price: Because not everyone is shopping on the same budget, our team included budget-friendly options and some suitable for big spenders.
• Safety: For some people, the thought of putting something glass in their tush can be intimidating. All the models in this review are made from high-quality, shatter-proof glass to ensure the wearer’s safety.

During testing, we rated each test criterion on a percentage scale from 0% (Worst) to 100% (Best). We then calculated the overall score using different weighted metrics depending on the importance of the test criteria. Half the total rating comes from Design (25%) and Safety (25%). After that comes Stimulations (10%), Build Quality (10%), and Price & Value (10%).

Everything We Tested

In this chapter, you can see a comparison table with all the products we tested. As you can see, each row has the test criteria our team used during the testing. To make our testing process even more transparent, we also included the raw test data so you can see how the products performed with each test criteria.

1. Crystal Delights Pony Tail Plug: Test Winner!

Why we love Crystal Delights Pony Tail Plug:

BDSM roleplay fans looking to get involved in pony fetish will love the Crystal Delights Pony Tail Plug’s detailed design. Everything, from the beautiful glass body to the long, glossy tail, which offered a mix of visual and aesthetic appeal, made it stand out. In addition, the team highlighted the premium borosilicate glass, describing it as beautiful and durable.

The well-thought-out design was the primary motivation when picking our test winner. Its unique space-shaped build worked like a charm. The tapered tip (closeup in the image below) simplified penetration while the graduating size promoted gentle anal stretching. More importantly, the slim neck made it easier for sphincters to clamp into the anal plug without causing discomfort. Its flared base, although tricky to regulate with lube flowing, enhanced security and avoided unwanted travel.

The long, black tail screwed to the base, giving the impression of a furry friend’s tail. The dramatic tail has a swishy and bouncy vibe that lets it move like real hair. Its stylish, cozy look and the 19-inch-long sheath gave the ‘ultimate main character’ feeling.

Stimulation-wise, the glass butt plug was more about the show than the intense stretching. The 1.3″ bulb diameter and 3.4″ length make it average-sized, but the alluring glass body and a long sheath provide a borderline overwhelming presence. The tapered body made it easy to slide the toy through the anal canal while the bulbous body induced a gentle feeling of fullness. However, the tail swishes to match every movement, which makes the experience worth it. “I have a huge mirror in my bedroom, and the sight of the dark tail swinging during masturbation and partnered sex made me feel unstoppable,” says Rachel Sommer.

While the glass butt plug is not one of those you wear as you carry on with your day, we loved that we wear it in the house during solo play, slutty photo sessions, and foreplay. You can also wear the furry piece as you binge your favorite TV series. “The reward was more visual, but I loved pairing it with a wand or a wearable clitoral stimulator.” The team also liked that, unlike most tail anal plugs, this product is gender-neutral with a simplistic styling that moves away from the pink and faux-fox cliché.

The build quality was also rated as above average. The company uses high-quality borosilicate glass, which is strong, smooth, and durable. The crystal-clear glass with dark sparkles inside the bulbous body gave it an alluring yet stocky feel that inspired trust that the toy would last a long time. The synthetic fiber on the tail felt more premium than anticipated, and the realistic swinging during play made the experience more visually appealing.

Lastly, the user experience was straightforward. The smooth material and tapered build made inserting the glass butt plug quick. Although the glass was weighty, the heaviness made it easy to guide it into place without much effort. Although the plastic threads felt finicky, the long tail made it easy to retract the anal plug.

Minor issues we found during testing:

Unfortunately, the screw at the base felt less premium than the rest of the glass butt plug. The plastic screw threads felt fragile, which begs the question why the brand didn’t consider a metal thread.

In addition, the flat, broad base got slippery with lube flowing, and adjusting the positions was trickier than other review samples.

Why Crystal Delights Pony Tail is the best glass butt plug:

• Design: Crystal Delights Pony Tail Plug’s spade-shaped design offers gentle stretching for beginners and intermediate folks. Its tapered shape and smooth borosilicate glass made sliding the piece inside the tight anal sphincters easy. More importantly, the wide, flat base offered anal sex safety, avoiding unwanted travel. Although synthetic, the thick black hair looked sleek and styled, with a smooth finish that made brushing it with the fingers cozy. It swished with every movement, dangling between the legs and creating an alluring visual appeal.
• Versatility: Although the long tail means you can’t wear it in public, we loved that the piece was resourceful during foreplay and slutty photo sessions with your partner. Its non-gendered design ditched the cliché purple and pink colors, allowing couples to enjoy sensory and aesthetic appeal. The glass also lets users explore temperature play by submerging it in cool or warm water before use.
• Build Quality: The company used high-quality borosilicate glass, one of the best sex toy materials. Although stiff, the smooth finish and the plug’s tapered build enhance the user experience. In addition, we appreciated the attention to detail evident in the glossy synthetic and spade-shaped design.

2. Icicles No. 48: Our Budget Pick!

Why we love Icicles No. 48:

For only $29.99, Icicles No. 48 is a massive bargain. Whether you’re a beginner seeking to explore the dynamic world of anal exploration or a seasoned collector looking to add another piece to the collection, the affordable price makes it perfect for different users. The beautiful glass, teardrop aesthetics, and robust build quality offer excellent value for money.

Besides the competitive pricing, our testers highlighted how the robust design made the glass butt plug stand out from the other budget models we tested. We didn’t expect much for the price, but we were impressed by the impressive attention to detail, evident with the daisy base, tapered build (seen in the below image), and smooth finish. According to our product test lead Sandra Larson, it felt more intentional than other models in the price range. “Most budget-friendly picks are more inclined towards visual appeal, but Icicles No. 48 was designed to offer more than looks: a snug fit without feeling bulky.”

The solid, no-flex design might be too much for newbies, but intermediates and experienced users will enjoy the rigidity. We also found the firmness and taper made it easy to regulate the position and land the anal plug where you need it the most. Although the dimensions were medium level (1.25″ diameter and 3″ insertable length), there was a borderline overwhelming feeling of fullness. “It felt present and intentional without spilling over to cause discomfort,” affirms Rachel Sommer.

Away from the practical tapered shape that made it easy to penetrate the anal sphincters with gentle stretching sensations, we loved the classic silhouette look with a glorious petal base. Its pink color was alluring to the eyes, illuminating any light source and making it a breathtaking sight.

Stimulation-wise, we loved how balanced the product felt inside. “I’ve used mine during solo masturbation and partnered sex, and nothing beats the ‘background-like’ feeling of fullness,” says Sandra Larson. “It doesn’t demand your undivided attention, but you’ll not forget about its presence.” The glass but plug shifts a little with each movement and you can pair it with other sex toys like wands and dildos for a ‘more complete’ experience.

The versatile Icicles No. 48 is perfect for solo users and couples. Besides offering a solution for people looking to massage the neck and other body parts, you want to dig into during foreplay (it’s marketed as a hand-blown glass massager), the anal plug also doubles as a temperature-responsive toy. It also works with any lubricant, and the alluring artwork makes it a jewel and a sex toy.

Lastly, the build quality was surprisingly good for a $29.99 sex toy. The company used premium borosilicate glass, a smooth, well-made, and durable piece. Its weight body made it easy to direct it to the desired location. In addition, the attention to detail was impressive, with the teardrop silhouette, tapered build, and petal-shaped base.

Minor issues we found during testing:

Unfortunately, the borosilicate glass, although premium, gets a bit slippery when lube is flowing. You must have a clean towel within arm’s reach to maintain control of the experience.

The daisy base was another alluring feature that made the piece stand out. However, it messed with the ergonomics, making it complicated to use for public play.

Why Icicles No. 48 is our budget pick:

• Price: Icicles No. 48’s $29.99 price tag surprised the testers because of its well-made design and impressive attention to detail, which was evident in the tapering, bulbous body, and flawless, smooth finish. Most of the glass anal plugs we tested had a price tag of over $50, making the Icicles No. 48 a massive bargain. Notably, the design language and build quality were impressive, making the piece an excellent value for money.
• Design: The simplistic design included an alluring teardrop silhouette with a classy petal base, giving it an ornamental look. Its pink color radiates any light source into a breathtaking sight, ensuring a quick look draws you closer to the sex toy. Our testers loved how the tapered shape simplified penetration and promoted gentle stretching. In addition, the weighted body made it easy to direct the anal plug to the desired spot.
• Build Quality: The borosilicate glass’s shatter-resistant properties make it more durable than delicate. The glass anal plug felt rigid, and even after months of repeated use, it felt and looked brand new. Our team highlighted the attention to detail evident in the alluring petal shape and teardrop silhouette.

3. Gläs Amethyst Rain: Beginner-Friendly!

Why we love Gläs Amethyst Rain:

Among the models we tested, we found Gläs Amethyst Rain to be the best for beginners. The well-measured dimensions (2.75″ insertable length and 1″ diameter) offered gentle stretching for newbies without feeling overwhelmed. In addition, the smooth glass finish and taper made it easy to slide through the rather tight sphincters.

The team also thought that Gläs Amethyst Rain’s comparatively short body (seen in the image below) made penetration short and quick, alleviating the mental blockage for first-time anal plug users. More importantly, the small and chunky body meant it didn’t just slide in and get forgotten: you can feel it tilt a little with every movement, and you won’t need reminding that you’re wearing a pleasure tool.

The anal plug graduating size that ends with a vast body before transitioning into a slim neck significantly enhanced retention. The transition was friendly to the sphincters, allowing you to grasp the toy without worrying about it popping mid-session.

As anticipated, the glass butt plug was more subtle than the other review samples. It won’t stretch you out fully, but it adds pressure to your solo play and partnered sex sessions. We also loved how gentle yet present it felt throughout the session: it won’t demand your full attention but will move with every clench and grind. “Think of it as a background singer that the audience can get their eyes off,” says Rachel Sommer. “But like the name, she stays in the background without taking over the show,” she added.

Our testers lauded the designer, highlighting how the size and graduated shape simplified the user experience. You don’t need much to start: grab your favorite lubricant, douche a generous dosage, and enjoy the bliss. Penetration was straightforward, and once inside, it stayed in place.

Versatility-wise, Gläs Amethyst Rain surprised us because of how resourceful it proved. Whether you want something to add spice to a lazy evening or revitalize your sex life by adding subtle fullness during sex, the model knows its role and plays it well. The best part about it? The elegant piece isn’t flashy, and you can pair it with other sex toys like wands and clitoral suction toys to amplify the sensations.

Lastly, the hand-blown glass looked stunning. The company used premium borosilicate glass, a shatter-resistant and non-porous material that looks and feels luxurious. In addition, the attention to detail was impressive, with a seamless finish devoid of air bubbles and gnashes.

Minor issues we found during testing:

Although the base seemed solid and durable, the broad and firm shape gets uncomfortable when you wear the piece for a long time.

The model is strictly for beginners. It’s easy to use and elegant, but those looking for a firmer and fuller feeling will be left yearning for more.

Why Gläs Amethyst Rain is the most beginner-friendly:

• Design: Our testers loved Gläs Amethyst Rain’s short and punchy design because it made penetration easy. Unlike other beginner-friendly models that were long but slim, its short length helped alleviate the mental blockade that makes anal exploration scary for beginners. The graduating size with a tapered shape, wider body, and slim neck made for seamless insertion and enhanced retention. In addition, its bulbous body ensures you always remember its presence, tilting with every movement and grinding.
• Versatility: While it might not be the most dynamic piece money can get you, we loved how Gläs Amethyst Rain anal plug adapted to different situations. When you’re enjoying a lazy afternoon watching Netflix, it slides inside the anal opening, staying hidden yet reminding you of its presence. Likewise, it enhances the quality of sensations during partnered sex and pairs flawlessly with other toys like wands and clit suction products.
• Build Quality: The designer used hand-blown borosilicate glass, a non-porous and hypoallergenic material. It looks and feels premium, with a smooth finish devoid of air bubbles and rough edges. Our testers loved the impressive attention to detail, highlighting the well-measured shape and taper that simplify penetration and make it the perfect first anal toy.

4. Chrystalino Tickler: Best Beaded!

Why we love the Chrystalino Tickler:

Chrystalino Tickler’s beaded design made it stand out among the review samples. Our testers loved how the slight design tweak offered unique sensations and versatility. Unlike traditional tapering, the differently-sized beads that got bigger towards the base provided a distinct bump as the sex toy entered and exited the body, making the sensations more elaborate.

The graduated beads added a unique feeling of movement, adjusting to every tilt during play, so you don’t have to do much to enjoy the anal plug. Our testers loved how the beads felt independent, which made the sensations elaborate. “Unlike other beaded models we tested, I could feel each bead slide through the sphincters, an intricate and thrilling experience,” Shane Davis told me.

The team also thought the progressive sizing made insertion manageable for beginners while laying the foundation for full-body orgasm when pulled out right at the climax. Its slow, teasing stimulation balances form and function, making it ideal for newbies and experienced folks. The best part about it? The rigid glass dildo meant there was no hiding; the beads let out their full wrath, making the stimulation intense.

Stimulation-wise, the firm glass, and the beaded shape meant its presence was never a secret. “It’s not one of those pieces you slide in and forget about,” says Rachel Sommer. “It stays present and demands your attention whether using it alone or pairing it with partnered sex.” She thought that each bead added a new wave of sensation, and the exciting series of aftershocks when pulling it out was breathtaking. In addition, the beads gave the user more control over the experience and offered a slow build-up to intense orgasms. Overall a solid design by the brand.

The user experience was also straightforward. Besides the beads offering more control, the tapered build made penetration easy. The gradual stretching gave the body time to adapt to anal exploration, while the loop handle made sliding the toy in and retrieving it bliss. More importantly, you can use the product with any lubricant, and cleanup is effortless.

Chrystalino Tickler’s build quality was rated as above average. The smooth, flawless glass looked solid without any bubbles or weak points. The evenly distributed blue color gave the model a luxurious look, while its satisfying weight made the sensations well-measured. As long as you don’t drop it on the floor, the piece should last long.

Lastly, the glass anal plug proved more versatile than anticipated. It was incredibly resourceful during solo sessions and partnered play. Whether using it alone or pairing it with a wand vibrator, the Tickler held its own throughout all kinds of play. The temperature-responsive glass lets users chill or warm the sex toy in water before playing for something more soothing.

Minor issues we found during testing:

Like other glass toys, things got slippery when lube got involved. Although the loop handle offered some reprieve, you must have a clean towel within arm’s reach.

In addition, the more experienced users will find themselves wanting more. According to our sexologist Rachel Sommer, the graduated beads provided gentle stretching, but it wasn’t the most filling anal toy.

Why the Chrystalino Tickler is our favorite beaded glass butt plug:

• Design: The Tickler’s beaded shape was the primary motivation when picking our test winner. The graduated beads got bigger towards the handle, offering gentle anal stretching and making the piece ideal for beginners. In addition, the individual beads provided a unique blend of sensations and slow teasing. Something else we loved about the design was the loop handle. Besides enhancing the user experience, its slim shape allows the sex toy to slip between the cheeks so that you can wear it for extended sessions distraction-free.
• Stimulation: Our testers highlighted how the beaded shape balanced form and function, making the rigid glass material easy to use. Unlike regular tapering, the individual beads offered a slow build-up to intense orgasms while giving the user more control over the intensity. The model’s presence is undeniable, and it’s not one of those pieces you slide in and forget about. More importantly, pulling the toy out left a series of thrilling aftershocks, making insertion as exciting as retraction.
• Ease of Use: Among the glass butt plugs we tested, Chrystalino Tickler proved to be the easiest to use. The beaded design enhanced the user experience and made penetration straightforward. Even for beginners, the gradual stretching allows the product to adapt while enabling you to control the number of beads that go in. In addition, the loop handle made it easy to slide Tickler inside and retrieve it.

Other Good Alternatives

Lovehoney Pure Pleasure is another alternative for beginners. Although longer than Gläs Amethyst Rain, the well-measured dimensions (4.5″ circumference and 4″ usable length) make it perfect for adventurous beginners looking to test their limits. Its smooth, tapered shaft made sliding through the tight sphincter muscles easy, while the flared base prevented unwanted travel. In addition, the thin neck was easier to grasp for the sphincters, allowing it to stay in place throughout the session.

Chrystalino Expert is a good option for people seeking an anal plug that feels cozy and filling even when worn for extended sessions. Unlike others which have a broad and flat base, the Expert’s ‘flirty’ T-shaped base slips between the ass cheeks without feeling uncomfortable. Its smooth edges feel exquisite even when you sit on a chair, making it perfect for public play.

Lovehoney Small Heart is an intricately designed piece that you’ll be looking forward to wearing, especially if you enjoy the sight of a glowing piece during solo masturbation or partnered sex. Its heart-shaped base was the highlight of the review, ensuring you don’t miss the lovely purple hue whenever you look in the mirror. Besides the aesthetics, the tapered tip graduates into a bulbous shape before slimming down into a thin neck. The ingenious design enhances the feeling of fullness while promoting easy insertion and retention.

Are glass butt plugs safe?

Yes, high-quality glass butt plugs are completely safe to use. Many products nowadays are made from borosilicate glass or other high-quality shatterproof materials and are guaranteed not to break during anal play.

But Why Should I Buy One?

Many people (like myself) swear by glass butt plugs, and we do so for many reasons. Most notably, the fact that they are made to be gorgeous. Whether in your bum or not, you can’t help but admire their gorgeous craftsmanship.

But besides being beautiful, butt plugs made from glass also offer some practical benefits. Unlike silicone butt plugs, which can harbor smell when used in your bum, products made from glass are insanely easy to clean, which is a nice touch for those who are short on time.

Just like metal toys, glass anal beads and other glass toys can also be used for temperature play, opening up a world of possibilities for those craving a variety of stimuli. [2]

How To Use A Glass Butt Plug?

After cleaning your toy, apply a generous amount of lube (silicone or water-based lube is suitable for glass). Then begin gently inserting the plug, tapered tip first. Take your time with this step, and stop momentarily if you experience any sort of discomfort. You can even do an anal douche, but it’s not absolutely necessary.
