Toyz4Lovers' Triple Pleasure Purple vaginal balls are perfect for pelvic floor training with Kegel exercises, thanks to the movement of the metal balls inside. Once inserted into the vaginal canal the three balls will cause the muscles to spontaneously contract, increasing the tonicity of the vagina for safe and easy training and powerful orgasms. The balls are made of hypoallergenic and phthalate-free silicone, have a soft touch surface and come with a practical strap for easy handling. The balls can also be removed from the frame for easy cleaning.
