Fun-Factory Smartballs Duo Light love ball

With the Smartball from Fun Factory, you can train your vaginal and pelvic muscles in a comfortable manner. Thanks to the ergonomic form, the balls can be easily inserted and have an extra strong loop for the highest safety. Strong pelvic and vaginal muscles provide for improved sensitivity and a better ability to have vaginal orgasms. The Ben Wa balls are made of soft silicone and there is a second, slightly oscillating ball inside. These oscillations train the muscles without any effort.
