Ultimate leak prevention, 12-hour wear, and less cramping and irritation

Easy to Remove

Patented ReleaseRingTM breaks seal and removes the cup in one smooth motion.


Designed for you and the planet, it lasts for years. Simply remove, wash, and reinsert.

12-hour wear

Prevents leaks for up to 12 hours for a full day or night of period protection.

How works.


Wash your hands. Press the sides of the cup together and then fold it in half again forming a tight “U” shape; OR place a finger on the top rim of the cup and press it down into the center making the top smaller for insertion.


Get in a comfortable position, relax your vaginal muscles, insert the FLEX Cup into your vagina, sliding it up and back toward your tailbone (not straight up).


Go and live your life as you normally would! You can swim, exercise, and sleep wearing FLEX Cup. It collects up to three super tampons worth of fluid for up to 12 hours.

Remove and Wash

Simply pull the ReleaseRing™ to break the seal and remove. The ReleaseRing™ pulls the top of the cup in to break the seal and help prevent spillage during removal. Before using or reusing, remove the ReleaseRing™ and thoroughly wash the cup for 20 seconds with soap and warm water.
