Our Kegal Balls are built for pleasure and to strengthen your pelvic muscles, which leads to stronger, more intense orgasms. Each ball contains a weighted bead that causes organic vibrations with your movements, stimulating and massaging you. As a tool to bring strength to your pelvic muscles, simply insert both silky beads and use your pelvic muscles to hold them in place. Try using them while doing yoga, or while in the shower or around the house. Women report after a few weeks of dedicated use they feel noticeably stronger.
