Innovation. This is the ONLY cup in the world that can be removed as easy as a tampon. We spent an entire year creating the "holy grail" of cups by combining shape with softness so you won’t feel it once it’s in place. Oh and that velvety pull-tab, it’s not like traditional cup stems, it’s super soft, flexible and even adjustable in length to fit your needs.
Sustainable. 100% reusable, lasts for years, creates zero waste & saves you money. The planet might just send you a thank you note.
Local Love. Unlike other cups, we make ours in the USA. Developed at a world-class medical device manufacturer, FLEX Cup is FDA compliant, made of 100% medical grade silicone and doesn’t contain toxins. Your vagina’s pH and natural lubrication can rest easy.
Perfect Fit Guarantee. We’re determined to get your size right. If yours doesn't fit, we'll switch it out for another size.

you got this

Insert - Wash your hands and the FLEX Cup for 20 seconds. 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).
Wear it for up to 12 hours.
Remove - 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 warm water.

Are you afraid to try it? We totally get it, trying something new can be challenging but once you nailed it, your period will never be the same. If you need help, our team of amazing FLEXperts are here for you at hello@flexfits.com

Unexpectedly love it

I was one of those people that thought menstrual cups were too complicated and just kind of messy. But I was so tired of searching for tampons and going thru so many of them every cycle with who know what kind of chemicals in them, that I finally decided to try the Flex cup and just see how it goes.

ITS AMAZING. So comfortable, easy to put in and take out. (Ive only been putting it in and out while in the shower, and I highly recommend this method). Still working out tiny leaks so I just wear a panty liner. All in all, this cup makes my period SO much more tolerable. I change/rinse it out in the morning and at night, then don't have to think about it all day and all night. Seriously, just try it.

Love it!

I wanted to try a cup for a while now and I’m glad I went with Flex! The instruction guide and website are so helpful to learn how to insert, remove, and clean. I will not be going back to tampons.

Why did I wait!?

No sense in dwelling...but man, the years I wasted on tampons, the frequent changes, unpredictable flows....not to mention the tax on the environment. I'm in my early 40s and just tried the flex cup and am so impressed! I had avoided using a disk or diaphragm after a gyno told me I had a tilted uterus and there wouldn't be any suction or adequate coverage. ??? Anyway, the flex cup (small size) was easy to use (great tutorials!) and lasted as long as I needed it to - we're talking 8+ hours! I'll never go back to tampons as my primary menstrual management. And it's covered/reimburseable by your HSA. Thank you for this stellar product.

Finally a cup that fits

I've tried a few different options and came across this one when I completed the Period Nirvana quiz, which turned out to be a godsend. Others caused me too much pain due to my inability to break the suction seal, and I was afraid to try the cup again for a long time until I found the Flex cup. Super easy to use, soft enough to be easy to insert, and had absolutely no pain when breaking the seal, using the pull-tab. Very happy I finally found something that works! :)

Try FLEX with some liners at first.

Sometimes you just feel better with a little backup. FLEX plus liners would be a great combination for you while you transition to FLEX to help guard against leaks until you get the hang of positioning FLEX.
