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.

Never going back

This is the first menstrual cup I ever tried, and I love it so much I would never go back to pads or tampons. Before, I was always having to guess if my flow would be heavy enough to use a tampon, because it is SO uncomfortable having to pull one out dry. The silicone of the flex cup slides out easily, even if you put it in on a day with no flow. I never feel it inside me, and I love that I can go 12 hrs before needing to empty it (can avoid public bathrooms and just do it at home before/after sleeping). Also the pull ring is a life saver when the cup rides up and the stem is slippery! I've never had an issue with removal.

Love my Flexcup!

I bought the flexcup back in February after dealing with an extremely heavy flow. I have PCOS and normally do not have heavy flows or periods during some months, but after having blood soak through a super tampon and a pad and through my clothes, I had enough and bought the flexcup. Being a first time cup user I was very hesitant, but I talked to several people who use regular menstrual cups and they helped ease any concerns I had. I had a little trouble first learning the insertion process, but even when I had issues with inserting, it still never leaked. I love the ring loop that you pull on to remove it. I was worried with a traditional cup that I wouldn’t be able to break the suction, but the flexcup breaks the suction for you. It’s amazing. I do feel a little pressure when removing, but nothing that can’t be handled. The only real problem I have with the cup is the stopper on the pulley system goes through hole at the base of the cup and it’s hard to put back in. I’m not sure if I’m pulling down to hard during removal, but this has recently started becoming an issue. Overall, I highly recommend this product.

I love this!

So I suffer from very bad cramps during my period, and my periods a very heavy. I usually have to go to the bathroom ever 2-3 hours to change my super plus tampons and pad. I had seen cups before and wanted to try one but was worried since none of them had a tab to pull. Then I saw an ad for Flex cups. Well I just started my period and I put the cup in as soon as I started spotting and I have gone all day with no cramps and no leaking! I absolutely love this product! I will never go back to tampons and pads again! The only thing that people should know is the first time it is a little difficult to get in, and when pulling it out it gets a little messy but I'll take that over a pain free period!

Wish I had this product years ago...

I first tried a menstrual cup in 2005. After about 20 minutes of trying to get the thing out, I finally called the company while she walked me through maneuvering my finger to try and get the suction to release. I struggled for what felt like forever, seriously considering going to get help at the ER. I finally got it out, but I never tried another cup again......until recently. After seeing the Flex’s pull tab, reading the reviews and then being offered a free cup for an honest review, I decided to give Flex a try.

Honestly, I wish I would have had this cup in 2005 instead of the other companies cup that I had tried. I ordered the full fit Flex and it works really well for my body shape and my heavy period flow. I’m about 110 but have given birth vaginally several times. Insertion has been super easy, removal is even easier!! I think it may have even helped with cramping too. Oh and no leaks...at all. (Removal has been pretty messy, but I think it’s one of those things that I’ll get better at in time.)

Also my daughter has the smaller slim-fit Flex and loves it as much as I do.

Great for my fellow thick women

I am a very plus size woman. I have a hard time reaching to grab a normal menstrual cup to take it out. The string on this cup makes it very easy to use and it never gets stuck. I vastly prefer it to tampons. My only wish is that the silicone was a little softer because it is a pretty sturdy cup and occasionally causes some light pressure during insertion and removal. Otherwise great would recommend

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.
