These balls are a unique addition to your kegel routine. The uniquely shaped dual balls are equipped with a sensor that allow the vibrations to begin only when they have been inserted. Then you can enjoy the sensual feel of vaginal vibrations while you work your pelvic floor muscles.
These balls are a bit weighty and the toy is not small, so we would not recommend it for beginners to kegel exercising.
