Why you’ll love Flex Disc

Designed for comfort

The rim's ComfortSeal™ technology warms and forms to your body for a
personal fit that keeps you comfy during exercise, sleep, sex and more.

Body-safe materials

No BPA, phthalates, or natural rubber latex. Only 100% medical-grade
polymers that don't host toxic bacteria or disrupt your vagina's natural
pH balance.

Fewer cramps

Because it sits in the vaginal fornix instead of the canal, 64% of Flex Disc users report fewer cramps while using the disc.

12-hour wear

The catch collects five times more blood than a super tampon AKA you can spend less time in the bathroom and more time living your life.

    Game Changer

    This product seriously changed my life! I used to have DEBILITATING cramps on my period.. maybe not every cycle but every other cycle I would spend at least one day, if not two or three days barely able to get out of bed. I would have cramps so bad that I almost passed out one time! The type of pain where you are literally closing your eyes and squeezing your fist to bare the pain... I tried taking Ibuprofen, drinking ginger tea, I even started taking birth control to try to help the cramps, and nothing helped. And then, I tried the Flex menstrual disc and just like *that*, my cramps just about disappeared! I don't really understand how, but I am so grateful! Now I can pretty much carry on like normal during my period. The pain is just a whisper in the background of my life, no longer shouting in my face! TYSM FLEX !!!! <333333

No abrasive drying tampons, no messy friction pads!!! I’m in love with these disc! Thank you for making my life easier and assisting me in having a more loving 🥰 relationship with my body and my cycle.

    Changed my life

    I will never look at a box of tampons the same. These flex discs have changed my life. I don’t know why or what the science is behind it, but after I insert it, my cramps are relieved unlike a tampon when the chemicals are releasing in our body, I cramp so much worse. I’m giving praise to whoever invented this because thank you from a woman who has excruciating pain painful periods to now finally getting some relief.

    The Best!

    I seriously love this product so much, I recommend it to everyone! It is so nice not to worry about leaks during long hours at work. I went on a long hiking trip this past summer and this disc made it such a breeze. Keep up the good work!

    I’m honestly surprised how easy it went in

    My weird anatomy can’t hold cups and this just went in like your average tampon I’ll definitely buy this again.
