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

ABSOLUTE GAME-CHANGER

Flex discs are so innovative. Once you try them out, you’ll never go back to tampons, pads, or whatever you’re using. They’re THAT GOOD.

Flex discs have gotten me so much more comfortable with my anatomy. Before using flex, I was honestly afraid of my vagina. Now I’m empowered and love my body even more.

The absolute best periods of my life. I never feel the disc while it’s in, and I have way less cramps. I never have vaginal dryness, either. They are so easy to use once you get the hang of them. I’ve been using flex for over a year now and I don’t hate my period anymore.

I had to use a tampon the other day because I forgot backup discs. It was awful. I never realized how much better my life was when I used flex discs. No string, no discomfort, no dry tampon to pull out when it’s time to change it.

I would give flex a million stars if I could.

Wow!

The first time I tried the disc, mind it was the first time I ever used anything other than a tampon or pad too, I was quite intimidated and it felt a little uncomfortable. I ended up giving up that first time. The second time however I figured it out and HOLY COW I am never going back. No mess, you hardly even know it's there! Bathroom trips are so easy now with no nasty pads or pee soaked tampons.

Best period product I have ever purchased!

Bye cramps!

I love this product, after learning how to "set" the disc properly I rarely need a liner. Cramping is almost gone. I'm so happy I decided to give it a try. Its changed my time of the month for the better!

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.
