Yoni Eggs are a simple, egg-shaped crystal that when inserted help encourage muscle contraction, resulting in benefits that range from bladder control to intensified orgasms. Because they are carved from crystal, not only do they strengthen the pelvic floor, but they strengthen the connection to yourself. Drilled yoni eggs come with a hole and string for advanced practices and easy removal, while non-drilled does not come with a hole making them slightly easier to clean.
