A menstrual cup is a reusable silicone cup that is inserted internally to catch and collect your menstrual flow, rather than absorbing it like a tampon.
It lasts up to 10years and keeps you covered for 10 hours. 2 sizes available.

Size A: is recommended for younger girls and a light to average flow. It holds 15 ml of menstrual blood which is equivalent to 2 regular tampons.
 
Size B: is recommended for a medium to heavy flow. It holds 20 ml of menstrual blood which is equivalent to 3 regular tampons.
