The double cone ball from Dorcel supports the strengthening of the pelvic floor muscles. It is strengthened by the metal balls that swing in the silicone housing simply while wearing. The egg-shaped balls made of soft silicone can be easily inserted with a little water-based lubricant and retrieved with the seamlessly processed return loop. In addition to the training effect, wearing them also has a stimulating effect. Just 15-20 minutes of wearing a day is enough to strengthen the muscles (more can also lead to sore muscles and tension).
