Crystal Glass Eggs by NS Novelties

Crystal Glass Eggs by NS Novelties are weighted medical-grade borosilicate glass trainers for pelvic floor strengthening. They combine functional muscle building with temperature play, delivering firmer grip and more intense orgasms through consistent use.

What it does

Inside your vagina, the weighted glass egg creates solid resistance against your pelvic floor muscles during contraction. Your muscles grip around it, generating immediate feedback about which areas are working and where you need to focus. Consistent training builds muscle tone and awareness, so every sensation during sex becomes more pronounced. Strengthened pelvic muscles grip tighter around a partner's penis during penetration and contract more powerfully during orgasm, creating more explosive climaxes that pulse through your entire core.

Glass conducts temperature exceptionally well. Run the egg under warm water for soothing sensations, or chill it briefly for an energizing jolt that increases blood flow and sensitivity. Sex Toys made from borosilicate glass like this one are non-porous, so they won't absorb bacteria or degrade with any lubricant type. Your pelvic muscles gain the control needed for extended arousal and multiple peaks, while the smooth surface glides effortlessly during insertion.

Fit and sizing

At 45mm long and 27mm wide, the Crystal Glass Egg is compact enough for comfortable internal positioning during both short training sessions and extended daily wear. Size alone doesn't determine fit—comfort and how the weight feels against your pelvic muscles matter far more. If you're new to pelvic floor training, this size suits gradual progression from 10-minute sessions up to longer passive wear. Cockringshop specialise in products for men and couples, and we stock a range of sizes and styles so you can find what works for your body, not what you think should work. Start conservatively and progress as your muscle awareness improves.

How to use it

Apply water-based or silicone lubricant generously to the egg and your vulva before gently inserting the rounded end first. Let the weight settle naturally inside your vagina where your pelvic muscles can grip around it comfortably. Begin with short 10-minute sessions, contracting your muscles in sets of 10 squeezes. Hold each contraction for 3 to 5 seconds, then release fully before the next rep. The substantial weight provides constant feedback, helping you identify and target specific muscle areas.

As your strength improves, progress to longer wearing sessions during daily activities for passive resistance training. Your muscles work continuously against the weight without active effort. For temperature play, run the egg under warm water before a session for soothing sensations, or chill it briefly for an energizing effect. After use, rinse thoroughly with warm water and mild soap, then pat dry and store in the included silk pouch.

Feature breakdown

Who it suits

Women rebuilding pelvic floor strength after childbirth will appreciate the gentle yet effective resistance that gradually restores muscle tone. Anyone experiencing decreased sensation during sex benefits enormously from enhanced muscle awareness and control, which translates directly to more intense orgasms and a better grip during penetration. Beginners can start with shorter sessions while experienced users progress to extended wear during daily activities. Those wanting to combine practical health benefits with sensual play will love the luxurious glass construction and temperature play options.

Skip this if you prefer something with more give or flexibility—borosilicate glass is rigid and firm, which is exactly what makes it effective for resistance training. If you dislike the sensation of weighted tools or find internal training uncomfortable, other pelvic floor approaches may suit you better. Anyone with vaginal pain, pelvic floor dysfunction, or recent surgery should consult a healthcare provider before starting any training tool.

How it compares

Glass eggs provide firm, unyielding resistance that doesn't flex or compress, making them ideal for building serious muscle strength through progressive training. Glass Prostate Toys offer similar rigid construction and temperature play but are shaped and sized for internal male anatomy. Silicone alternatives flex slightly, offering a softer sensation but less direct resistance feedback. Glass conducts temperature much more effectively than silicone, so if temperature play appeals to you, glass delivers more noticeable sensations. Choose glass if you want durability, clarity, and firm resistance; choose silicone if you prefer flexibility and a gentler feel.

What you can use it with

Pair the Crystal Glass Egg with Couples Intimacy Kits to strengthen your pelvic floor while exploring partnered play together. Stronger pelvic muscles grip tighter during penetration, so training with these eggs directly enhances the sensation for both partners during sex. The improved muscle control also means you can sustain longer contractions during intercourse, intensifying pleasure for both of you and creating more powerful shared orgasms.
