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.

Must Try!

I've been looking at the flex cup for a few months now. I've read every possible good and bad comment made about it. Not many were bad, so I gave it a try. It has been one of the best purchases of my life! I had Toxic Shock Syndrome from using tampons (which is why I was looking for an alternative) and since using this produce I haven't had an ounce of pain! There is a very small learning curve (like don't just rip it out, I made a huge mess lol) but it's eco-friendly, cheaper in the long run, didn't leak for me, and comfortable.

Highly recommend!!!

Hi mamas!!

Highly highly recommend this flex cup. Was nervous because I only ever used tampons. For a first time cup experience this was TOO EASY! To think I am helping save the environment was constantly having to throw away nasty tampons, makes me feel soo much better about having a period! Was nervous about inserting for the first time, but if you fold it in half and go straight back not up it’s really simple. I put it in and thought “that’s it?!” Also super comfortable. Which is a plus. Personally, think it is more comfier than a tampon. If you are afraid you’ll leak through where a panti- liner. Atleast with the cup you don’t have to change it out as often as a tampon!

Love the idea but think it maybe doesn’t fit right...

I feel like it deserves more than a 3 but not quite a four, let’s go for a 3.8. I love it for my lighter days but it seems like it doesn't seal properly for my heavier days...and yes I make sure it’s completely unfolded. Within an hour it’s already leaking and not more than half maybe 3/4 the way full. Not sure if it just doesn’t fit me right or what the deal is. But I do plan to continue using it on light days :)

I highly recommend this product!

I had a painfully traumatic experience with diva cup so I was skeptical about flex cup but I wanted to try it because it seemed easier to remove thanks to the pull tab. On my heaviest days, my period is abnormally heavy. I would leak through an ULTRA tampon after 3-4 hours. That’s how long the cup would last before leaking too. Even though the cup didn’t last longer than a tampon on my heaviest days, I still prefer it because I am afraid of TSS from tampons (I think the risk increases with higher absorbency)

Why I love the flex cup:

-saves money on period products over time

-no links to TSS

-no guessing what absorbency of pad/tampon to use on any given day (has anyone else ever inserted a tampon and it came out mostly dry 8 hours later?)

-Easy to insert and remove once you get the hang of it (2-3 cycles until I felt 100% comfortable)

-Less leakage than tampon while sleeping even on heaviest nights


2 months before writing this review, I started a birth control to make my periods lighter. The cup has been EVEN better now that I have a lighter flow.

Highly Recommend!!

I've been using the flex cup for about 6 months and I love it!! Inserting wasn't as difficult as I thought after I found the method that worked best for me (I do the c fold) and found the right size. I first ordered the slim fit because I had never used a menstrual cup before but it leaked a lot. I thought I was putting it in wrong but when I realized I didn't have leaks on my lighter days I decided to go up to the full fit size and I was not disappointed. I have a very heavy period (using multiple ultra size tampons a day on my heavy days) so I wear a pad with it while I still get used to using and figuring out how often I need to empty it. Removing has been more of a learning experience - I think I was threading the release ring too far and since I've been more conscious of that I haven't been having as much of an issue.

Highly recommend!! Definitely stick with it and give yourself time to learn before you give up - it takes time!

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.
