These beautiful, solid glass Ben Wa Balls are linked with a nonporous silicone strap. The silicone's soft texture becomes slick when lubricated, and is waterproof so you can enjoy these Ben Wa Balls anywhere. Both the glass balls and silicone strap can be run under hot or cold water to deliver sexy thrills or chills. The straps make for easy insertion and removal. 

Silicone is durable, nonporous, and can last a lifetime.
