Cora Reusable Period Disc The price tag of the Cora Reusable Period Disc ($30) may seem steep at first, but when cared for properly, it can be used during your period for up to 10 years! Like many other discs, it can be worn for up to 12 hours at a time, which the brand claims is the absorbency equivalent of about five to seven tampons.
