What Is A Menstrual Cup?
The first patent for a menstrual cup was registered in the 1860s but only became commercially popular in the 2000s, thanks to higher awareness and activism against plastic pollution contributed by disposable pads and tampons. It is a soft and flexible bell-shaped device with a stem designed to sit in the vagina and collect menstrual flow; once it is full, the user simply removes it, empties and rinses it, reinserts and repeats the process until the end of the cycle.
