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

16 Year Old

So I am 16 years old, and very active. I am a competitive swimmer and volleyball player. Tampons had always been what I used, but I would leak or have to change them so often. I started seeing ads for the flex cup on Pinterest, I saw that you can go up to 12 hours without changing, or leaking! My mom and I started looking into it. I also loved that it reduced waste. (I have seen a noticeable difference in the amount of trash in my bathroom trashcan than before) It was a little hard to use at first it probably took me 2-3 cycles to get it without any problems. I used the slim fit first, I began leaking probably after 1 year of using the slim fit, now I have started using the full fit and there is no more leaking. Making sure to get the right size for your body it is key to no leaking. I also change mine in the shower, I felt like this was the easiest for me personally. I love this product and would definitely recommend to athletes and girls that are very busy.

Love at first flex

Let me start this review by being very candid- I originally bought my flex cup package for the flex discs. It was 10pm, I was distraught, my period had just started a few days too early and I was in need of a product to use for period sex. I grabbed the flex cup off the shelf at target and figured I’d give it a whirl, however the flex discs low key scare me— the ring is a daunting size. I did not end up using the discs have yet to even try, but ended up falling in love with my flex cup. A couple days after my flex disc fiasco I finally put my flex cup to use, immediately I ran into my sisters room and said I just discovered the best thing ever. I’ve been using my flex cup for 6 months now, and tell every single woman I know to buy one for themselves. All of the women in my family use flex cups, two of my coworkers happily made the switch, I even bought my friend one for her birthday. We are all extremely happy to be saving money on tampons, reducing our waste and having mess free periods. I currently have the slim fit, and I will say on heavier days I have to dump more often than 12 hours (the cup does hold about the same as two super sized tampons for reference) but I’m typically able to manage this before I go somewhere or when I get home so I haven’t had an issue in a public restroom. As for when I go to sleep, if I’m really concerned I’ll use a panty liner. The pull tab is the perfect length, and on days I have a more normal flow, I’ll honestly forget I’m on my period…

Best thing for women.

Some people are disgusted by an Advertisement that is a natural part of being a woman. If we can't openly talk about period blood, then there is something wrong with society. So grow the eff up and learn to have these discussions. I ABSOLUTELY f@$#ing love my cup. I just ordered the larger size to accommodate my heavier flow days. The slim is nice on my light days, but when it is so heavy, I have to dump after 4 hours. Only a pain when having to be in public areas. I save money from not buying tampons that I know are toxic and I don't have to feel like I am wearing a diaper from pads. My vajayjay doesn't get dry and all I gotta do is wash my hands. I am never going back to those products. Diva cup all the way.

Wish I learned of this sooner

I started using a menstrual cup a couple years ago to be able to exercise comfortably and sleep without worry of making a mess of my sheets without using tampons and diaper thick maxi pads. While I loved it for the reasons I got it for, I always had trouble reaching far enough to get it out. This cup however gives me the benefits my previous cup while being much easier to remove. My only regret is not knowing of this and trying it first but I plan on sticking with this brand for future replacements.

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.
