The Loving Joy Silicone Pleasure balls are a wonderful fun product that combines playful teasing with important pelvic floor toning. Internal clay balls within each smooth silicone shell create the feeling of a vibrating movement as they roll around. The Loving Joy Silicone Pleasure Balls in Purple are made in the best quality material and can be warmed to body temperature or cooled for different sensations. A looped silicone retrieval pull chord remains outside the body for comfort and ease when removing the Pleasure Balls. Each jiggle ball measures 7.5cm x 4cm. Keep the Loving Joy Silicone Pleasure Balls in great condition by using them with water-based lubricants only and cleaning with an antibacterial sex toy cleaner after every use.
