"The only menstrual cup in the world that can be removed like a tampon"

Flex Cup is so easy, you already know how to use it. The patented pull-tab breaks the seal for easy, beginner-friendly removal. Plus, it lasts for years saving you money and creating zero waste along the way.

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.
  • 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.

Watch our how-to video here
  1. 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).
  2. Wear it for up to 12 hours.
  3. 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

My only regret is I didn't get this years ago

Just used my flex cup for the first time a few days ago and it was so easy. I was very skeptical but had heard good things about mensural cups and I was tired of the waste that tampons create. It honestly feels way more comfortable than a tampon ever did. Once it's in place you can't even feel it and removing it was a breeze. Just pull softly so it doesn't jet out like a rocket ship (lol). I'd say the learning curve is about 3 days - I'm on day 4 now and I already feel like a veteran. My only regret is I didn't get this years ago. Plus, I did the math and I'll be saving about $100 - $130 a year now that I'm a converted cup user. Amazing product!

Convenient but messy!

I love that you can leave it in for 12-hrs without worrying about it - especially overnight! I also love that you are helping the environment by refusing pad & tampon use. However, it is so messy!! When you pull the string to break the suction blood gets all over your hands. Haven’t found a way to prevent this.

Life Saver

I've never left a review before, but felt like it's important for anyone interested in this type of product.

I am a person who loathed periods so much and had such bad cramping that I chose a variety of depression-inducing bc for years rather than put up with a very short cycle. I loved being able to not worry about spotting, esp as an active athlete, but finally made the decision to stop bc as it was destroying my mood. I took a chance with Flex cup as my first alternative to tampons and genuinely can't believe how good it is. The first day I was expecting awkwardness putting it in, pain, bulkiness, anything- but it was like not having anything there like advertised. I exercised and stretched like normal, and found it helped with internal cramping. I'm so happy this exists, it also saves on so much waste and generally makes me feel comfortable and at peace again. Definitely try this if you're on the fence.

Bye bye Tampons

Ive seen this ad, and many other period cup ads online and decided to give it a try. I picked this one due to the release string and after using it for 4/5ish months I’m very pleased with my purchase. Now, to be honest my first 2 months were rough... since this was my first time using a cup I believe I didn’t insert it properly and it leaked and then when I pulled the string I pulled too hard and it leaked, basically a disaster. It is a transition, but it is worth it. I paired this with the pixie cup steamer (life saver) and it’ll definitely save $$$ in the long run and help the environment.

Game changer!

I have been researching menstrual cups for about 6 month’s and I finally decided to pull the trigger and get a flex cup. Honestly, I’m so happy I did. I was never the girl who could wear tampons without pain, so I always wore pads with a medium/ heavy flow . The flex cup with only using it for one cycle has changed so much for me. Insertion was a lot easier then expected as well as removal, (i had a lot of anxiety about it). I couldn’t be happier with my purchase. My husband said it was a much better period for him as well because I wasn’t moody from being uncomfortable!

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.
