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

Excellent product

I bought this product from Walgreens and was kind of skeptical at first. But let me say that flex exceeds my expectations. It was easy to use and you can't even feel it's there. I also like that you can have sex and don't have to worry about a bloody mess. I will definitely be buying this again in the future. Thank you for this lovely product and saying goodbye to tampons.

Easier than I ever could have imagined

I was sick of changing my tampons every 2-3 hours, leaking everyone, the horrible feeling of tearing out a dry tampon, etc. I moved to cups and I tried a few, I even tried the flex cup with the pull tab and that WAS nice, but still not as comfortable taking out. I finally decided to try the disc, scared of its large size, but oh my god. The disc is so much easier to place and pull out than a cup. I don't feel it at all. This disc is a miracle. If you have used a cup before this will be CAKE for you.

My pants and panties (and wallet) all thank you!!

Recently a wish to feel like a teenager again was fulfilled, but not in a way I or any woman would have wanted. Lol! I had been having an issue lately with overflow 🙄 Every Single Month! At LEAST once I would stain a new pair of pants, sometimes while I slept other times in broad daylight 😳 SOOO EMBARRASSING!! I have used pads since Aunt Flo first started visiting, I have tried tampons, but end up cramping 100 times worse with them and basically gave up on that being an option. I was desperate for a solution to my problem that wouldn't also leave me curled up in a ball for a week once a month... along comes a flex disc advertisement. First time I saw this thing, I thought, ha! No way that'll work for Me! Though by now I was So over traditional methods and unwilling to spend SO much on "period panties" (sounds embarrassing, because I go to the laundromat to wash my clothes) I hit my peak of SO $*&@ING DONE with my period and happened a across a box of flex available at the store. I looked it over, took a deep breath and put the box in my cart. The only overflow experience since that day has been of pure joy! Relief! No more mad dash to the restroom first thing in the morning, no more worrying if there's a giant red spot showing on my behind, and NO product induced cramps! Thank you for this product ❤❤❤

Legitimately the greatest period product ever

I had switched to a cup because I was looking for a healthier alternative to tampons and I really hate pads. I tried several types of cup but my cervix is in an unusual position and was never totally comfy with them. I tried several reusable discs and none fit quite right. Flex is by FAR the most comfortable internal period product I’ve ever used. I actually forget I have my period when I use it.

It's Amazing!

I started my period the same day Flex arrived. It was 2 day's late and I swear my body knew it was coming haha, but as soon as I started my period I followed the easy steps inserting it and I can not even tell I have anything protecting me. The sex was easy with NO mess at all!! Lady's it's the best thing ever. My daughter is 12 and she is very athletic I am going to have her try it as well to see how she feels when she is doing cheerleading and basketball. I think she will love it!! Thanks guys it's amazing!!

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.
