Fun Factory Smartballs Duo jiggle balls are made with velvety soft silicone right down to the removal loop, which means they are easy to clean and very skin safe.
The Smartballs Duo has been updated with a cleverly-designed tapered head, making insertion much easier and improving overall comfort. The first ball is also smaller than the second ball which aids gradual insertion.
The movement of the balls within the vagina causes the pelvic floor muscles to tense and relax, which strengthens them over time, making them tighter and more toned. Unlike some other similar products on the market, Smartballs Duo is very quiet when in use.
Although the Smartballs Duo is not primarily a sex toy, continued use of jiggle balls in a Kegel exercise regime can lead to improved arousal, stronger orgasms and strengthened pelvic floor muscles: ideal for those with health conditions such as bladder weakness.
