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

Great product

occasionally leaks due to tilt of my cervix and placement. It takes a bit of practice.

Great product!

Great product! On my heavy days I was having to use the ultra tampon size and I was still having to change it every few hours. Got tired of that and decided to try the Flex Disc. Can't feel it when it's in and I can go way longer than I could with a tampon or pad. Only have had it leak once and that was because I went too long on a really heavy day (my bad). Sometimes messy removing it but the benefits outweigh that - I usually just plan my day so I can change it at home. My only complaint is the change from the black wrapper (discreet, quiet) to the clear plastic wrappers. It's a noisy way to conceal a crime scene.

My opinion

This is only my opinion but I believe this is the most disgusting YouTube advertisement clip I have ever seen. Who cares if someone likes their vagina, and who truly needs such description on how to use these item. Clean it up girls try to be a little more ladylike. Or has this generation forgotten what the word ladylike means.

I don’t feel gross anymore!!

I don’t know why I’ve always felt disgusted by myself while on my period. I never associated it with the products I was using, but this disc has kind of changed the way I see myself as a woman on her period and I feel more confident about it now. This disc helps with the odor, feeling clean all day instead of getting that elevator scene in The Shining every time you go bathroom... I can make love with hubby and he can’t even feel it, and NO MESS!! The only thing I don’t like, is they changed the packaging from Sleek black softouch Discreet baggies, to clear LOUD crinkly transparent plastic baggies. Not cool. Change them back please.

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.
