"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

Best menstrual cup on the market?

I had been using a Lunette for 6 years and thought that menstrual cups just had to be kinda difficult to use. Sooo glad I came across Flex as I was looking to get a new cup! I have been using my Flex cup for a few months now and have nothing but good things to say. The design that allows you to break the seal from the stem = genius. And the stem itself makes it so much easier to remove. I also just love that the cup is black so I don't need to be confronted with years of period stains as it gets older!

I have been worried about getting an IUD because I use a menstrual cup, but I'm finally game to try it with Flex - will report back!

Best Purchace Ever

I bought the flex cup back in April and it was well worth the price. I've taken 5 or 6 hour car rides, gone on planes, went swimming for hours with friends and family, and have done so many things with this cup in. not having to worry about if a tampon is leaking or bleeding through my pants, not having to change the product every few hours is amazing. I absolutely love that I can put it in in the morning and not worry about it until I get ready for bed. 100% worth switching over to it and we'll worth the price. the pull tab is what made me specifically buy the Flex Cup and it works wonderfully. I absolutely love it!!!

Amazing and a must have if your tired of Tampons!

I absolutely love this product! This is my second time using the flex cup and it’s been a life saver. I am on the implant birth control so my periods can be irregular and change heaviness all the time. I bought the slim fit for my first time and haven’t even leaked yet! I hated using tampons because in the early days of my period I’d leak though them at night and I just simply hate spending so much money on them. I barely ever feel the cup, and although it took me a little while to figure out how to effectively put it in, I now fell in love with it! If you hate buying tampons all the time this is definitely something for you!

Amazing!!

First time user here and will be a forever user. I struggle with PCOS so my periods are never "normal" I ordered this 2 weeks ago when I was 2.5 weeks into my period because after two weeks I was raw from taking tampons out every time I went to the bathroom and hated wearing pads 24/7 for over two weeks. I received it a week ago after my period had ended. Jump forward a few days after I got it and I had to stop taking my birth control pills so I got another period. So far I've only leaked once and I've been using it for 3 days. I can get out and go shopping without stopping at the bathroom at every store. I can run and play with my kiddo and dog. Even went to the fair and rode rides with it! This is a God send I can be normal on my period! Ive also noticed I am cramping less and I don't feel it either. Another bonus for me is that I don't have to get up 2-3 times a night ro change tampons and pads. This thing is amazing. The pull tab is adjustable and just like a tampon which makes it very easy to remove!

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.
