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

This is the cup - the best cup for beginners, for period pros, and for people who are tired of outdated menstrual care. The pull tab makes this cup easier to use than any other cup. Plus, it lasts for years saving you money and creating zero waste along the way.
FLEX Cup comes in two sizes so you can choose the perfect fit for your flow and your body. Not sure which one is for you? Don't stress. If your cup doesn’t fit, we've got your back and switch it out for another size. We highly recommend to start with the Slim Fit .

BONUS! This pack includes 2 FREE Menstrual Discs. Many of our customers switch between using FLEX Disc and FLEX Cup throughout their cycle, depending on their flow, what activities they’re doing, and overall what’s most comfortable for them.

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

so excited to have found one that works!!

before i bought flexcup i bought the diva cup and it was painful and honestly kind of traumatic to use for my first time, i tried it 3 times before i told myself i would never try a period cup again because it was painful and kind of scary for me but then i saw the flex cup with the pull "string" to break the suction seal and i thought i'd give period cups one last chance because i really wanted to not use so many wasteful tampons. the first time i tried the flex cup (i got the beginner one) i felt like my whole period experience just changed. it was comfortable, EASY to get in and out and most importantly, not painful!! i would recommend this product a thousand times over!! if you are scared to try period cups or you have tried and feel like you will never try it again, give this one a shot! i was right there too and i'm so glad i tried one last time

The best one out there!

I usually don't write reviews but I felt like this deserved one. I have tried using a menstrual cup for a while now but the other brands that I have tried before were very unsuccessful. I was able to put it in for the first only after about 3 tries. and then the next day I was able to put it in successful on my first try. I love the way the Flexcup is designed similar to a tampon when removing it which is very familiar to me. It made it very easy to remove. I am very happy with my purchase! thank you :)))

I was hesitant to try at first but definitely glad I did. It’s a bit difficult to get used to at first but after a few tries, google, and exploring what works for you it gets much easier. The pull tab is definitely awesome and the reason I purchased this specific one, I’m not afraid it’ll rise up and get stuck. I do wish the pull tab was a stronger material to ease the worry that it’ll break on me:( I purchased the slim fit, as I’m in my early 20’s and haven’t given birth, the actual cup is very soft but thicker than others I’ve seen so it takes a little getting used to. Otherwise I’m happy with it, especially where It can be used for all flows and stay in for 12 hours! So worth a try for beginners.

Have the best period of your life!!

Run do not walk to get your hands on flex! Finally a period product designed by women for women that actually works. I love both the cup and the discs. Never had a better period; I always feel clean, comfortable, have less cramping, and can feel good about creating less waste every month. The cup comes in a slim size, which is a game changer for beginners. I tried other brands of cups and was never successful, but with flex slim I pretty much nailed it on the first try. In case it’s helpful to anyone else, I find it helpful to use a small amount of a water-based lubricant when inserting the cup. Made it so easy especially the first couple times while getting the hang of it. And now I never have to go back to awful tampons/pads. What a fantastic company, thank you Flex!!

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.
