only the best

What we put in our bodies is important. You don't have to make compromises with FLEX. Our products are safe for your body, regulated by the FDA, and made with supreme care and consideration. No chemical bleaches, no toxins, no issues. Only the good stuff.

why it's special

  • Reliable. No more running to the bathroom every few hours - one disc holds as much as 3 super tampons with 60% less waste.
  • Flexible. It was made to fit most people, including mamas & teens to keep you safe from your lightest to heaviest days. And we know what you’re thinking: “This Disc looks HUGE”. It’s actually about the size of a tampon when you squeeze it :)
  • Comfortable. Many of our customers thought having a dreadful period was a fact of life they just have to deal with - until they tried something new. FLEX can’t be felt at all once in place.
  • Safe & Sustainable. 60% fewer cramps and 80% less dryness & irritation compared to traditional period products. Hypoallergenic, not linked to TSS, made of 100% medical grade polymers, FDA approved, cruelty-free, vegan.

you got this

Watch our how-to video here
  1. Insert - Wash your hands, pinch the disc in half and insert it into the vaginal canal by pushing the edge that goes in first down toward the floor. Tuck the rim above your pubic bone.
  2. Wear it for up to 12 hours.
  3. Remove - With clean hands, slide your finger up under the front edge of FLEX Disc and pull straight down, keeping it parallel to the floor.
  4. Dispose- Turn disc upside down to empty in toilet. Place the empty disc in a wrapper and dispose of in the trash.

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. The disc can’t be felt at all once in place. If you need help, our team of amazing FLEXperts are here for you at hello@flexfits.com

Go ahead and buy it!

I haven't been able to use tampons comfortabley since having my daughter 4 years ago. I could always feel them, they would slip out, and wouldn't absorb properly. After trying different brands and switching to pads, which felt that diapers, I explored other options. I came across menstrual cups and chose Flex because I liked the hoop on the pull tab and thought it would be easier to get a hold of when it was time to remove.

This thing is amazing! You don't feel it and it doesn't leek. You honestly can set it and forget it. I bought the smaller one even though I've had a baby and it fits like a dream. My only regret is waiting so long to do the switch.

NO ABSTRACT SHEETS OR CRAMPS!!!!❤

So I wish I would have tried the disk the first time I made fun of the youtube commercial because Kara was on point with that period sex bit. Also minimized my cramps.... I did have a minor set back when I couldn't find it I was frantic but once I squared and relaxed a bit I got ahold of it. Even with the messy insertion and loosing it for a moment I will never ever go back NEVER!!!!! AMAZING TO SAY THE LEAST!!!! Thank you Flex you have changed my life and I won't have to throw out so many pairs of underwear either. Lol

Life Changing

I will never buy another box of tampons in my life!! I have the heaviest periods (1 super plus tampon might last me an hour) so it gets expensive. I ran across the ad for Flex on Facebook and saw everyone raving about it so I bought a box. I was a little worried about not being able to get it out so I didn't try it right away but after changing my tampon for the 3rd time in 2 hours yesterday I tried it and I am hooked!! NO CRAMPS, EASY TO REMOVE, NO LEAKS, VERY COMFORTABLE!!!!! I am so excited to never have to wear another tampon. If you are on the fence with this product, don't be. It's a life changer.

Flex cup is Amazing

I have a condition called Endometriosis and have tried many different brands of menstrual cups and they have failed to work for me. I have extremely heavy menstruals and can't deal with the side effects of birth control to regulate it. I have been able to wear the flex cup for 7 hours straight with no leaks....Today is my first time using it so I took it out early out of curiosity, lol. I'm normally changing my super+ tampons every few hours and wear a pad with it because I will still leake heavily at the beginning of my cycle. I just so amazed by this product....literally the best product I've found to help me in years.

PLEASANTLY surprised!

You had me at period sex lol I haven't experimented YET. Meanwhile, the first insertion was uncomfortably easy and I was very skeptical. The first removal wasn't as easy and I thought "oh no! I'm one of the 'it got stuck' people I read about!" But then I bore down WHILE reaching for it and out it came! It's been a breeze ever since. I'm now on my third insertion, no leaks, completely comfortable, still wondering if it's too good to be true lol I'm sold!

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.
