What it does

Borosilicate glass absorbs your body temperature instantly, creating natural warmth that builds arousal as you use it. Unlike softer materials, this glass won't compress under pressure, so every thrust delivers firm, consistent contact against your vaginal walls. Glide it in with lubricant and the smooth surface slides effortlessly. Position the curve toward your belly button to angle directly at your G-spot.

Flowing ribs along the shaft massage your G-spot as you rock or thrust, stimulating nerve endings throughout your vaginal canal. Firm pressure builds tension steadily, triggering increased wetness and sensitivity with each movement. Weight creates natural momentum that amplifies each stroke, helping you reach deeper orgasms that radiate from your core. Browse our full range of Sex Toys to find other options that suit you.

Fit and sizing

At 3cm diameter and 15cm insertable length, this dildo suits most anatomy comfortably. If you're new to glass toys, the smooth surface makes a forgiving starting point — though if you've never used a glass toy before, you might prefer something smaller first to get used to the firm texture and weight. At 456g, this is substantial, so it rewards confident users who know they enjoy firm pressure and G-spot contact. Cockringshop specialise in products for men and couples, and we stock a range of sizes and styles to match your comfort and experience level.

How to use it

Apply water-based or silicone lubricant generously to both the dildo and your body before insertion. Insert the curved end first, angling it toward your belly button so the shape targets your G-spot directly. Start with gentle rocking motions to let the flowing ribs massage the area, then increase to longer thrusting movements as arousal builds.

Listen to your body's responses. When you feel that deep ache building in the right spot, maintain that exact angle and speed until you peak. Firm glass holds its shape under pressure, so you can thrust harder without losing contact. After use, wash with soap and water and dry thoroughly.

Feature breakdown

Who it suits

This dildo works best for people who already know they enjoy G-spot contact and want something firmer than silicone. If you crave that full, substantial feeling during penetration, the 456g weight delivers exactly that. You'll appreciate glass toys if you like firm, uncompromising pressure that doesn't give way under thrust.

Skip this if you're completely new to penetrative sex toys or prefer flexibility and give in your materials. Complete beginners to glass might find the weight and firmness intense, so starting smaller makes sense. If you dislike the sensation of firm pressure or prefer sex toys that flex slightly, silicone remains a better choice.

Tested and quality-checked

Every new line we stock is hands-on tested before it ever goes live — we power it up, run it through its functions, and check it for safety and for how it actually performs. Overseas orders get a second function-test right before they ship, so a dead motor never reaches your door. Nothing is used for its intended purpose; it is checked, inspected, and re-boxed. What that means for you is simple: the unit you open is one we already know works. See how we test every product →

How it compares

Glass differs fundamentally from silicone: it's rigid with no compression, so pressure stays consistent and targeted no matter how hard you thrust. Silicone flexes and warms gradually, offering a softer, more forgiving feel. Glass conducts temperature instantly, letting you play with heat and cold; silicone doesn't respond to temperature play. If you're exploring other glass options, our Glass Prostate Toys collection shows how the same material works for different anatomy and purposes.

Please read — safety first. Put the ring on before you are fully erect and use plenty of water-based lubricant so it slides on without pinching. Keep wear time short — no more than 20 minutes while you are getting used to it, and never fall asleep wearing one. Take it off straight away if you feel numbness, coldness, a change in colour, or any pain, as these mean blood flow has been cut off too far. Never share between partners without cleaning the item first or using a fresh condom. This information is general in nature only and is not medical or professional advice, and does not take your personal circumstances into account. Stop use and speak with a qualified medical professional if you have a relevant health condition, take medication for erectile function or blood pressure, or notice pain, numbness, or discolouration that does not settle.

What you can use it with

Pair this dildo with Couples Intimacy Kits if you're using it with a partner — they often include complementary sex toys or positions that let both people participate. Glass toys combine well with other firm sex toys during partnered play, and the weight means it stays in place without constant effort, freeing your hands or your partner's for other contact.
