A Diva Cup is a brand of menstrual cup, which is a menstrual hygiene device that is inserted into the vagina during menstruation to collect menstrual fluid. Menstrual cups are usually made of flexible medical grade silicone, latex, or a thermoplastic isomer and are shaped like a bell with a stem or a ring. The stem is used for insertion and removal, and the bell-shaped cup seals against the vaginal wall just below the cervix and collects menstrual fluid. Unlike tampons and menstrual pads, which absorb the fluid, menstrual cups catch and collect the flow. The Diva Cup is a reusable menstrual cup designed to fit the users body and flow for up to 12 hours of continuous protection. It is made of medical grade silicone, is BPA-free, and has no added chemicals, plastics, or dyes. The Diva Cup is recognized as a reliable product that is easy to use and is one of the best-known brands of menstrual cups.
