MoonCatcher menstrual disc is a shallow, wide and flexible bowl made from 100% medical silicone.
Prior to insertion the MoonCatcher disc is pinched by the middle so that it becomes about the size of a tampon and is then placed high up in the vagina to collect menstrual fluid for up to 12 consecutive hours.
No suction is needed to keep the disc in place. When the MoonCatcher is full, just remove, empty and rinse it in water. It is now ready to be reinserted.
