Reusable menstrual cups and discs are sustainable period products that can be used as an alternative to traditional pads and tampons. Menstrual cups are bell-shaped cups made of silicone, rubber, or latex that are inserted into the vagina to collect menstrual blood. They can be reused for up to 10 years with proper care. Menstrual discs are similar to menstrual cups but they fit into the fornix (where the canal and cervix meet) instead of sitting in the vaginal canal below the cervix. While menstrual discs can be single-use, there are also reusable options available.
