Scarlet Couture Glass Duo Balls by Adam & Eve Sextoys

Two weighted glass spheres that strengthen your pelvic floor muscles while delivering subtle arousal during daily wear. Perfect for building stronger orgasms and enhanced sensitivity, these borosilicate balls work through gentle internal pressure and natural muscle engagement.

What it does

Insert these glass spheres into your vagina and your pelvic floor muscles naturally grip to hold them in place. As you move—walking, climbing stairs, or doing household tasks—the balls shift slightly, creating gentle pressure against your vaginal walls. This constant low-level contact builds awareness and sensitivity in your intimate area while the smooth glass surface absorbs your body heat, adding a temperature element to the muscle workout.

Over time, the muscle contractions required to keep the balls positioned strengthen your pelvic floor tone, leading to a tighter grip during penetration and sharper, more intense contractions during orgasm. Increased blood flow to the area heightens nerve sensitivity, and you'll notice growing wetness and arousal as circulation improves throughout your session. Products like Love In Leather can complement this internal training with external sensation during partnered play.

Fit and sizing

At 1.2 inches per sphere, these glass balls suit most women comfortably, if you're new to pelvic floor training or already experienced. Beginners appreciate the moderate size and secure retrieval cord, which lets you wear them for extended periods without anxiety about removal. Experienced users value the solid glass weight, which creates more muscle engagement than lighter alternatives. Since these sit entirely inside your vagina, external sizing isn't a concern—focus instead on comfort during wear and your ability to hold them confidently. Cockringshop specialises in products for men and couples, and we stock a range of Love Eggs and Kegel Exercisers to suit different preferences and experience levels.

How to use it

Apply water-based lubricant to the spheres and gently insert them one at a time, leaving the silicone retrieval cord outside your body. Your vaginal muscles will naturally grip around them—you should feel their presence but never discomfort. Start with 15 to 20 minute sessions to let your muscles adjust to the workout, then gradually extend wear time as your strength improves.

Move around normally during wear: walk, climb stairs, do household chores. Normal activity creates the shifting motion that both engages your muscles and builds arousal. Remove the balls by gently pulling the retrieval cord while bearing down slightly with your pelvic muscles. Rinse with water or toy cleaner after each use, and store in a clean, dry place. Dishwasher-safe for thorough cleaning if you prefer.

Feature breakdown

Who it suits

Women who want stronger orgasms through pelvic muscle training will appreciate these balls' dual function. Beginners benefit from the moderate size and secure retrieval system, while experienced users enjoy the solid glass weight that creates more muscle engagement. You'll love them if you want to build pelvic floor strength discreetly during everyday tasks, or if you're interested in the subtle arousal that comes from internal pressure during normal movement.

Skip these if you're pregnant, menstruating, or have pelvic floor dysfunction without medical clearance. They're also not suitable if you need external vibration or texture to become aroused. If you prefer lighter alternatives or have very sensitive vaginal tissue, a different style of Love Eggs and Kegel Exercisers might suit you better.

How it compares

Glass balls deliver solid, sustained internal pressure and temperature play, while silicone versions flex slightly and warm faster to body temperature. Glass holds its weight longer during wear, creating more continuous muscle engagement, whereas silicone offers a softer, more forgiving feel. If you want a completely different experience, Japanese Love Dolls offer full-body intimacy. Choose glass for serious pelvic floor training with temperature sensation; choose silicone if you prefer comfort and flexibility.

What you can use it with

Pair these glass balls with Couples Intimacy Kits for partnered play that combines internal training with external stimulation and shared pleasure. Wearing the balls during partnered sex intensifies sensation for both partners—your tighter pelvic floor grip enhances penetration, while your partner benefits from increased muscle tone and control. The training also deepens your awareness of your own arousal, making partnered sessions more responsive and connected.
