A silky set of silicone-wrapped weights from Shibari, the Pleasure Kegel Balls revamp a classic, making pelvic-floor strengthening easily customizable and extremely pleasurable. Two possible versions of the Ball- a single and a double- are tucked securely into individual silicone girdle, each featuring a flexible looped handle for easy placement and removal. Once in place, the strategically weighted spheres inspire contractions of the vaginal muscles. Over time, the Pleasure Balls help strengthen and tone the pelvic floor muscles responsible for sexual pleasure, control and orgasm enhancement, while pinpointing the movements needed to practice kegels without the balls in place. Beginners should start off with the single ball at 1.4oz (40g), graduating up to the double 2.8 (80g) combination when ready. Aside from the practical applications of this strengthening system, wearing the Balls can help to increase sexual awareness as the free-form weights within gently vibrate and jiggle. The Pleasure Kegel Ball set is worn completely internally, so you'll be able to wear a chosen ball combo unbeknownst to anyone, anytime and anywhere. The entire set is of a high end silicone, a material that's completely body safe, phthalate free and extremely hygienic, not to mention hypoallergenic and perfect for users with sensitive skin. Each Ball measures 1.25 inches (3.2cm) in diameter.
