A 1000 year old design - reinvented!
Designed to give vibrating pleasure long before vibrators, motors, or even electicity were discovered, Ben-wa balls had a weight inside them that moved and vibrated with the body's own motion and muscle contractions. These K-Balls do the same thing with the added benifit of being covered with 100% silicone so they are hygienic and easy to clean. They're great for exercising the Kegel muscles (thus the name) and have a cord for easy retrieval. Comes with bonus booklet of Kegel exercises.
