Gläs Amethyst Rain Butt Plug Review

There’s something kind of magical about glass butt plugs. They’re smooth, shiny, a little mysterious – and way prettier than they have any right to be. The Amethyst Rain Hand Blown Glass Plug by Gläs doesn’t try to be anything wild or gimmicky. It’s just a good-looking, well-made toy that feels cool (literally and figuratively) and does what it’s meant to do.

In this review, I’ll talk about what it’s actually like to use a plug like this, why I think it’s a great pick for beginners, and how it stacks up against other plugs I’ve tried. Spoiler: it’s simple, elegant, and surprisingly satisfying.

Key Takeaways

The Gläs Amethyst Rain Plug is simple, classy, and surprisingly effective for such a small, quiet thing. It’s a great entry point into glass toys – firm, pretty, and built to last. It’s not trying to be edgy or extreme, but it definitely has a presence once it’s in place.

It pairs beautifully with a wand, thrives in warm-up scenarios, and makes a solid case for why more sex toys should double as décor. Not for size queens or stretch-seekers – but if you want to feel elegant and just a little wicked? This is the one for the job.

Who Should Try It? If you’ve ever been curious about glass toys – or already own a few and want something simple, elegant, and easy to use – the Amethyst Rain is a smart choice. The size is manageable, the shape is forgiving, and the sensation is subtle but very much present. Perfect for solo sessions, partner play, or just walking around with a little secret.

Who Can Skip It? If you’re looking for stretch, pressure, or heavy fullness – this one might feel a bit too gentle. Also, if you’re super new to anal and worried about firmness, glass might take some getting used to. And the base, while safe and smooth, is wide enough to be noticeable in certain positions.

You Can Buy It on the Peep Show Toys website for $20.

What Is the Gläs Amethyst Rain Plug?

The Amethyst Rain Plug from Gläs might sound like the name of a moody indie album, but it’s a sleek little piece of hand-blown butt jewelry – and a very beginner-friendly one at that. Shaped like your classic plug (tapered tip, bulbous body, long neck, wide base), it keeps things simple in the best way.

Made from borosilicate glass – the same fancy stuff they use in lab beakers and bougie bakeware – it’s smooth, sturdy, and totally up for some temperature play. It’s got just enough weight to feel present without being intimidating, and unlike silicone, it doesn’t squish or bend. This thing stays exactly where you put it. Which, if you’re like me, is kind of the whole point.

First Impressions & Features

Unboxing

As you can see in the image below, the Gläs Amethyst Rain Plug comes in a no-fuss box that actually does the job – basic, clean, and blessedly accurate. The image on the front shows you exactly what’s inside (no weird surprise sizing or deceptive glam shots), and the plug is tucked in snug with a foam insert and – hallelujah – a soft little storage pouch. It’s not luxury packaging, but it’s not tacky either. More “quiet confidence” than “discreet brown wrapper.”

The plug itself? Genuinely pretty. That soft amethyst tint has this pearly, almost iridescent glow that catches the light just right. It doesn’t scream look at me, but it definitely whispers damn, that’s nice. You can feel the quality in your hand – cool, smooth, and ever so unique thanks to the hand-blown finish. It’s giving glassware with benefits.

How Do I Use the Amethyst Rain Plug?

To use the Amethyst Rain Butt Plug, start with clean hands, your lube of choice, and a bit of patience. It’s firm and super smooth, so it’s naturally easy to insert – but don’t skip the lube. Use more than you think you need, especially if you’re new to glass toys.

Insert slowly, letting the tapered tip do the work. Once the bulb passes the anal opening, your body will naturally hold it around the narrow neck. No need to push or force it – if it’s not going in comfortably, pause and add more lube or relax a little longer.

The wide base keeps it safe. It’ll sit snugly against your skin and won’t travel anywhere it shouldn’t. Because it’s lightweight and has a long neck, it’s also pretty comfy to wear for longer periods if that’s your vibe.

If you’re curious about temperature play, this plug is perfect for it. Just run it under warm or cool water for a few seconds before use – never freeze or boil – and test the temperature on your wrist first to avoid any surprises.

My Personal Experience

I’ve used glass dildos before, and I’m familiar with the quality of the Gläs brand – so when I saw the Amethyst Rain Plug, I figured why not add something a bit more wearable to the mix? I already have one of their 10.5” girthy beasts that only comes out when I’m feeling extra brave, so this felt like a more manageable, everyday kind of option.

I picked it up on a whim, mostly because the shape looked easy and the light purple tones happened to match my current 80s vibe (think glass tile bedroom window feature and disco beats). Yes, I’m that person. Ambiance matters.

The first time I used my new plug was on a slow solo evening. I warmed it under the tap, slicked it with silicone lube, and slid it in while casually reading erotica. The sensation was immediate – nothing squishy, no bend – just solid, cool presence. Glass doesn’t try to mimic flesh. It just sits there, confidently, asking your body to do the talking.

What surprised me was how comfortably it stayed in place. I wore it while using a wand, and the internal pressure from the plug gave every vibration more punch. It didn’t slip, didn’t distract, and didn’t pull focus. It was just there, doing its job like a quiet overachiever.

Later, I tested it cold. Whole different experience. The second it touched me, I flinched with a half gasp, half grin. It wasn’t painful, but it lit everything up fast. And during partner play? Honestly, it felt like butt-lingerie. No one could see it, but I knew it was there. That secret little sparkle between my cheeks gave me a weird, sexy sense of control. And a bit of a strut.

Design

Simple geometry, done well. The Amethyst Rain Plug sticks to the classic formula – tapered tip (closeup in the image below) for easy entry, a smooth bulb for that satisfying little stretch, a slim neck to help it stay put, and a flat, wide base so it doesn’t wander off. There’s a reason this shape has stood the test of time: it just works.

What sets this one apart is the glass. It changes the whole experience. The firmness adds presence, the temperature responsiveness makes it feel more alive, and the finish is so smooth that your body picks up on every shift and nudge. You don’t just shove this in and forget about it. You insert it with a bit of intention – and that attention kind of sets the tone for everything else.

The base is solid and safe without being clunky. It sits flush against the skin and doesn’t get in the way. And while the overall shape is pretty standard, the amethyst tint adds a little something extra. Not flashy, just quietly gorgeous. Like the sexy cousin of a chemistry beaker.

Material

This plug is made from borosilicate glass – the same tough stuff they use in lab beakers and fancy French bakeware. It’s smooth, non-porous, and hypoallergenic, so if your body tends to throw a tantrum at unknown materials, this one’s a safe bet.

Cleaning? A dream. I’ve boiled it, rinsed it under hot water, and yes, even tossed it in the dishwasher once after a particularly lazy weekend. It came out gleaming. There’s no smell, no stickiness, no mystery residue. Just a cool, clean surface that feels ready to go whenever you are.

Stimulation

The Amethyst Rain Plug isn’t the kind of sex toy that takes you for a ride on its own. It’s quiet. Subtle. More of a pressure player than a full-on stretch. But if you move with it – clench, rock, grind a bit – it gives that feedback in a very deliberate, very delicious way.

Think of it as background depth. You won’t finish just from wearing it, but when paired with a wand, a partner, or just the right mindset? It seriously elevates the experience. It’s teasing, but in a way that makes you want to chase that edge.

Build Quality

This is handblown glass, and it shows – in the best way. There’s a weight to it that feels satisfying in the hand. No air bubbles, no sharp spots, no uneven seams. The base is smooth and comfy where it needs to be, and the whole thing just feels… well-made. Like someone actually paid attention while making it.

It’s surprisingly luxe for something this affordable. Honestly, it gives off the vibe of a custom piece without the boutique price tag.

Ease of Use

Beginner-friendly in the best way. You don’t need to overthink anything – just grab your favorite lube (any kind works), slide it in slowly, and enjoy. It’s super easy to insert, and once it’s in, it stays put without fuss.

The only heads-up? It’s still glass. Strong, yes – but if you drop it on tile or smash it against a faucet, you’ll want to give it a close inspection. Tiny cracks can be hard to spot, so just give it a quick once-over before every use. It’s like a wine glass: treat it well, and it’ll treat you even better.

Versatility

Where this plug shines is in its ability to shift gears with your mood. Lazy solo evening? It’s the kind of toy you can slip in, forget about, and then suddenly remember in the best way when your wand hits just right. With a partner, it becomes a secret little showpiece – something elegant and a bit filthy. Not flashy, just… present.

And if you’re the kind of person who keeps lube and a bowl of ice water on the nightstand? You’re in for a good time. The temperature play options make this feel like more than just a plug – it’s a prop, a ritual, a bit of theatre.

It’s not built for marathon wear or complex tricks. But for quick, beautiful, feel-every-movement pleasure? It’s spot on.

Minor Issues I Found While Testing

The base is wide and firm – which is great for peace of mind, but not so comfy if you’re planning to sit cross-legged with it in. It’s better suited to lounging than yoga poses. Glass doesn’t budge. There’s no squish, no forgiveness, so if you’re new to anal toys, take your time. Lube well, breathe, and don’t rush the entry.

While it’s elegant and easy to wear, this plug is on the lighter side. If you’re into plugs that really hang out and give you that heavy, full feeling? This one might feel a bit too polite.

Alternatives to the Amethyst Rain Butt Plug

Rosebuds Small Aluminum Plug

If metal’s more your thing (or if you’re after something that feels like jewelry for your butt) the Rosebuds Small Aluminum Plug is a luxe little pick. It’s lighter and smaller than the Gläs Amethyst Rain, with a sleek anodized aluminum finish and a crystal base that’s more about discreet sparkle than showy glass. The base is flatter and more subtle, which makes it comfortable for longer wear or for pairing with partner play. Plus, it’s French. Which just adds to the whole “secretly fancy” vibe.

Chrystalino Tickler Glass Plug

If the Amethyst Rain feels a bit too chill and you’re after something with a little more action, the Chrystalino Tickler is worth a look. Instead of one smooth bulb, it’s got a line of soft glass beads that give a gentle pop as they slide in – way more sensation, even if the size is still beginner-friendly. It’s made from the same smooth glass, so you still get that luxe feel and temperature play bonus, just with more movement and fun. Kinda like if the Amethyst is a slow dance, this one’s more of a cheeky little twerk.
