A period product unlike any other

Discs And Tampons Comparative 1 Disc = 3 super tampons

You can wear it for up to 12 hours and it is conveniently disposable. It collects blood instead of absorbing it, reducing dryness & irritation. If reduced cramps sound good to you, look no further. FLEX sits above the vaginal canal where it can move with your body and can’t be felt at all. Sleep through the night, swim or enjoy mess-free period sex. Ready to challenge your period as well?

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

Perfect for Pelvic Pain Girlies

I was super skeptical about trying anything other than a tampon. I’m allergic to pads so I’ve used tampons for most of my periods. After developing Interstitial Cystitis I was left with severe chronic pelvic pain and tampons became super painful to use. My Pelvic Floor Physical therapist gave me a few flex cups to take with me and try. I was concerned that they would still cause pain. It just looked really uncomfortable. However I can honestly say I’m in love with these flex cups! The flex cup never adds additional pain to what I’m already experiencing, It’s so comfortable I sometimes forget I even have one on, there is little to no leaking. Maybe some slight blood when I wipe but nothing crazy, and this is a way cheaper option than period panties! I always recommend these!

Where can I invest?

I’ve been using the FlexDisc for awhile but hadn’t yet embraced the idea of using them during any bedroom action. I took the (literal) plunge yesterday during the reddest of possible red days and there wasn’t a Single. Drop. Anywhere. And…we weren’t exactly gentle with it. Where have you been all my life?

Helps cramps and dysphoria!!!

I have PCOS and have only had a period once every year or so for most of my life unless I used hormone treatment. I'm now 38 and have had a monthly period for the last 9 months. I know part of my problem was that I wasn't used to having a period, but it's also the only time I experience gender dysphoria. I feel my body isn't mine when I'm on my period and having to change products regularly. Then came the flex disc! I originally intended to use a cup but got a size that was too large, so I tried the disposable disc that came with the cup. WORLD CHANGER! My cramps were reduced, I didn't have as much mess, it wasn't as uncomfortable, I could insert and remove easily on light days, and not worrying about my product for 12 hours helped the dysphoria more than I can say! I'm only giving it four stars because it was a little too firm for my liking, but switching to the reusable disc fixed that issue perfectly.

Doesn't work at all

I don't know what the problem is, I've tried inserting it in every position I can. sitting, one leg up, laying down in several positions. the diagram shows there should be room for your finger to go in before hitting it but it sits right inside the opening no matter what I do, aside from trying to fist myself not pinch or pushing makes it go in any further and it pops out when I sit down to pee (like sticks out of my vagina). I use menstrual cups normally and thought it would be like them but this thing is huge! why is it so big around? how on earth are you suppost to get it to stay inside?????? not buying again and mad that I have a whole box of useless items.

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.
