"The only menstrual cup in the world that can be removed like a tampon"

Flex Cup is so easy, you already know how to use it. The patented pull-tab breaks the seal for easy, beginner-friendly removal. Plus, it lasts for years saving you money and creating zero waste along the way.

#1 Recommended Cup by Cosmopolitan Magazine

We highly recommend to start with the Slim Fit. (unless you've had 2+ vaginal births), but we'll work with you if it doesn't fit, and may replace it with the other size.

BONUS! This pack includes 2 FREE Flex Discs. Many users prefer to switch between their cup and discs depending on their flow and what activities they're doing. (Psst... the disc allows for mess-free period sex.)

Ingredients

why it's special

  • All-Day Wear. Keeps you safe from leaks and mishaps for up to 12 hours, so you can spend your day sleeping in, staying up late, or doing whatever makes you happy.
  • Innovation. This is the ONLY cup in the world that can be removed as easy as a tampon. We spent an entire year creating the "holy grail" of cups by combining shape with softness so you won’t feel it once it’s in place. Oh and that velvety pull-tab, it’s not like traditional cup stems, it’s super soft, flexible and even adjustable in length to fit your needs.
  • Sustainable. 100% reusable, lasts for years, creates zero waste & saves you money. The planet might just send you a thank you note.
  • Local Love. Unlike other cups, we make ours in the USA. Developed at a world-class medical device manufacturer, FLEX Cup is FDA compliant, made of 100% medical grade silicone and doesn’t contain toxins. Your vagina’s pH and natural lubrication can rest easy.
  • Perfect Fit Guarantee. We’re determined to get your size right. If yours doesn't fit, we'll switch it out for another size.

Watch our how-to video here
  1. Insert - Wash your hands and the FLEX Cup for 20 seconds. Press the sides of the cup together and then fold it in half again forming a tight ‘U’ shape. OR place a finger on the top rim of the cup and press it down into the center making the top smaller for insertion. Get in a comfortable position, relax your vaginal muscles, insert the FLEX Cup into your vagina, sliding it up and back toward your tailbone (not straight up).
  2. Wear it for up to 12 hours.
  3. Remove - Simply pull the ReleaseRing™ to break the seal and remove. The ReleaseRing™ pulls the top of the cup in to break the seal and help prevent spillage during removal. Before using or reusing, remove the ReleaseRing™ and thoroughly wash the cup for 20 seconds with warm water.

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. If you need help, our team of amazing FLEXperts are here for you at hello@flexfits.com

GAME CHANGER

This is the best cup ever. No pain on the urethra coming out, no mess, so easy! The pull out tab is made of soft, pliable silicone that does not poke or irritate like other cups. I work 12+ hour shifts and cups are perfect; others are uncomfortable and I dreaded removing them due to the pain I experienced. THANK YOU, THANK YOU, THANK YOU. Perfect for beginners and those who need a new cup also! Most ingenious product ever and definitely the best thing I’ve ever bought for my feminine health!

Honesty! The switch was challenging but I love it

I'm honestly writing this because I felt really alone when I made this switch, at first. All the reviews make it seem like people effortlessly made the switch to a menstrual cup and that was not how it was for me. I'm a long distance runner, mountain biker (all bikes, really), and field paleontologist and I hate the environmental impact of disposable period products but have always been intimidated by a menstrual cup. Recently I had my IUD taken out and for the first time in 4 years began having a cycle again and finally decided it was time to do it. The first day of my first period if 4 years was a challenge and I had a hard time finding the right position what worked for my body and new menstrual cup. After the first day I was sad, exhausted, and SO frustrated because I just couldn't figure out why I couldn't figure it out. I finally decided to message someone at Flex and am beyond happy that I did. Four different women listened to me and asked questions about what was going on and I finally figured out what I needed to do and what worked for my own body. This is my third day with it and I'm really happy I stuck with it and remained patient. Prior to my IUD I had such terrible periods that my husband would find me on the ground in pain due to cramping and so far, the cup has severely decreased my cramps which is a damn miracle and worth the original frustrations. I can't recommend this company enough or this product!

Never going back!

Two years ago I decided to try a diva cup since I hated pads and I read a horror story about tampons lol! I found flex cup and loved the idea of the easy pull removal. After using it for a while I will never go back! I spend most of my summers out on the lake and it is great to use the flex cup because I don’t have to worry about changing a tampon. I have recommended this to all my girl friends and will continue to recommend it!

surprised how great it is

I expected it to not work for me and was pleasantly surprised, also seemed to reduce cramps, and is very comfortable to use, I have only used it for 1 period so I am hopeful. As a nurse working long hectic shifts I dont have time to change menstrual products sometimes 2 or 3 times an hour on heavy days. I am happy I have this product.

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.
