We highly recommend to start with the Slim Fit. (unless you've had 2+ vaginal births), but we'll work with you if it doesn't fit, and may replace it with the other size.

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.

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

Got the wrong fit but they were nice about it :D

So I got the wrong fit for the cup and when I contacted the company, they were very nice and patient! They texted back almost immediately and we got the problem resolved. I didn't have to pay shipping or anything. Really nice company and is very comfortable

Second chance at a cup - GAME CHANGER!

I tried a menstrual cup years ago and swore I would NEVER try one again. Insertion was uncomfortable, it leaked like crazy, and trying to remove it was a horrific experience involving many swear words, a near full bottle of wine, my husband, and (honest to god) a pair of pliers. It was a nightmare.

When I heard about the flex cup and the handle/seal breaker, I decided to give the menstrual cup one final try. Oh. My. Gosh. This thing is a GAME CHANGER! Not only is the silicone far more comfortable to insert, but the ring style handle makes getting the thing out possible and super easy. I purchased the slim fit, which leaked a bit, but the customer service team is super knowledgeable and personable (you’re never getting automated messages, it’s always an actual person) and walked me through different insertion and positioning techniques to try to eliminate the leakage. I ended up needing the full fit, and this company sent one - just like the box promises - completely free. This is absolutely the cup to try if you’re thinking about making the switch from tampons. I’m always surprised how much blood it holds, how little it leaks, and how little I even notice I’m wearing it. Also (BIG plus here), you know that feeling of trying to remove a tampon that’s not full? It’s awful. It’s all scratchy and pulls and sometimes kind of painful? That NEVER happens with the Flex cup. Whether it’s full, half full, or empty, it’s easy and painless to remove.

Overall so incredibly satisfied…

A life changing product!!

I cannot recommend this product enough! I'm from the UK and currently there is no cup on the market like this (with a pull ring) within the UK. The flex cup made conquering my fear of using mental cups a million times easier, and I will never look back now! I tell all of my friends and family about this product and they have also converted from using conventional period products. Thank you Flex Cup for this life changing product! :)

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.
