The Moressa Osian Chinese Balls are covered with 100% high-quality silicone. They have an elegant design in three colours and an incomparably soft, comfortable and velvety touch. Osian 3 is the ideal accessory for pelvic floor training, especially for beginners and women with a tilted uterus. They are inserted like a tampon, and just like a tampon, OSIAN is virtually imperceptible. During your daily movements, the constant but silent internal rotations create involuntary muscle contractions that strengthen the muscles of the pelvic floor.
