Sirona Reusable Menstrual Cup With Pouch Medium is Sirona's bestselling FDA-approved menstrual cups. It is made of 100% medical-grade silicone, offers 8-10 hours of leakproof protection and complete freedom from rashes. This is a biocompatible, toxin-free, odourless and hypoallergenic material which can be inserted into the vaginal canal to collect menstrual fluid. The flexible rim of the menstrual cup creates a vacuum seal that ensures there are no leakages or spills, regardless of how much you move. You can use the menstrual cup for period protection even when you swim, dance, play sports or travel. Sirona Reusable Menstrual Cup solves the problems of restricted movement, rashes, dampness and leakage due to the usage of sanitary pads during periods. A single Sirona Menstrual Cup can be used for 8 hours at a stretch and lasts for up to 10 years (though, it is recommended to replace your menstrual cup once every 3-5 years), making it the most pocket-friendly option for managing periods.
