Crystal Premium Glass Kegel Large

Strengthening your pelvic floor doesn't have to mean sacrificing sensation. The Crystal Premium Glass Kegel Large combines precise muscle training with luxurious glass construction, giving you both function and aesthetic beauty in one hand-blown tool.

What it is

The Crystal Premium Glass Kegel Large is a hand-blown Borosilicate glass exerciser designed for serious pelvic floor muscle training. Its substantial 9-inch length and gradual width progression create a progressive resistance experience that rewards controlled insertion and sustained muscle engagement. The transparent construction reveals subtle internal patterns, making it as visually striking as it is functionally effective. Unlike silicone alternatives, glass delivers superior temperature responsiveness and a weight that heightens sensory awareness during use.

This tool stands apart through its combination of durability and precision. Borosilicate glass resists thermal shock and maintains integrity through years of use, while its non-porous surface ensures complete hygiene without material degradation.

How to use a glass sex toy

Wash the Crystal Premium Glass Kegel Large thoroughly with warm water and mild soap before first use. Apply water-based lubricant generously to both the toy and your body. Begin by gently positioning the tapered end at your vaginal or anal opening, then slowly insert at your own pace. Allow your muscles to adjust to the progressive width as you move deeper. Once fully inserted, use controlled internal contractions to grip and manipulate the glass.

Temperature play opens new sensory dimensions—warm the glass in hot water or cool it in the refrigerator before insertion for dramatically different sensations. Experiment with different positions to engage various muscle groups and discover what your body responds to most strongly. You can incorporate traditional Kegel exercises while wearing it, focusing on sustained contractions and releases. For enhanced support during extended wear or training sessions, consider pairing this with Sex Slings to maintain comfort and positioning.

Care and storage

Clean your glass kegel immediately after use with warm water and mild soap, paying attention to any textured areas. For complete sterilization, boil the glass for five minutes or use a dedicated toy cleaner. Dry completely with a soft cloth before storing in the provided protective pouch. Keep it in a cool, dry place away from direct sunlight, and avoid dropping or subjecting the glass to sudden temperature changes.

Mistress Athena's training notes

By Mistress Athena — professional dominant and kink educator, sole instructor behind BDSM Australia's library of training videos. Read her full bio →

This glass kegel has become central to my control protocols. Its weight and transparency create immediate psychological presence—submissives become acutely aware of their own responses the moment it's inside them. Temperature play adds another layer; warming or cooling the glass shifts their focus entirely, making them hyperaware of sensations they'd normally overlook. Control deepens when the body can't hide its reactions.

My submissives learn precision through this tool. I demand specific contraction patterns—holds of exact duration, releases timed to my commands. The glass's rigidity means there's no slack, no escape from the work their muscles must perform. Watching them struggle against their own physiology, seeing the moment mental surrender catches up with physical effort, reveals exactly where their discipline needs strengthening.

Advanced training uses temperature variation strategically. Alternating warmth and cold conditions their nervous system, sharpening their ability to focus despite distraction. Some of my most dedicated submissives have developed remarkable endurance, maintaining position and muscle control through extended sessions. This device teaches them that true submission involves mastery of their own body first.
