These are the best quality, genuine and natural jade ben wa balls you can purchase.  Jade has been used for centuries for eggs and kegel exercise for women because of the qi energy compatibility.  Ying Yu Jade ben wa balls are made sized to Chinese medicine standards by our jade carver in China who buys the jade stone directly from the jade mine and carves them to our high standards.
