Flex Disc is not reusable. Flex Disc is a single-use, disposable menstrual product that has been tested and approved for up to 12 hours of wear. After 12 hours, you must remove Flex Disc and dispose of the used disc in the waste bin, then you can insert a new one.
Once you remove Flex Disc, even if the 12 hours has not been reached, you must dispose of that disc and insert a new one. Flex Disc should only be used as directed.
