These benwa balls are designed for internal pleasure. The balls features a double-layer design that allows the inner ball to move freely within the outer ball. The silicone material is velvety soft, hypoallergenic, and phthalate-free. An added benefit, is that women can use these balls to exercise their pelvic muscles, resulting in sexual benefits such as increased sensitivity and tightness.
It's suggested that this exercise is performed 3 times a day with a set of 10 (one contract, one release counts as one). Be careful not to overexert. This can cause muscle fatique and urine leakage.
