“Flex was designed to solve many of the problems caused by traditional menstrual products. It doesn’t change the vaginal flora reducing the risk of infections and has not been linked to toxic shock syndrome.”

3 tampons

is easy to use

Pinch.

FLEX may look big but it’s actually smaller than a tampon when you insert it. Start by washing your hands and pinching it in half.

Insert.

Use your index finger to guide the front edge, tucking it up behind your pubic bone. You shouldn’t be able to feel it at all if it’s in the right place.

Wear it for 12 hours.

Swim, workout, have sex, go to the bathroom, sleep, all without having to worry about leaks or changes.

Remove.

Always start with clean hands. Take a seat on the toilet and slide your finger up under the front edge of FLEX and pull straight down, keeping it parallel to the floor.

Dispose.

Once you've removed FLEX, turn the disc upside down to empty the fluid into the toilet, place empty disc in a wrapper and dispose in the trash.

Read the Directions

I was initially unimpressed because the cup would leak every time i went to the bathroom. BUT it says in the directions that this will happen!!! The amount it leaked wasn't even enough for it to get into my underwear though, so i realized that it was not a big deal. You really do forget you are on your period. I had one issue where it lost it's seal in the middle of the night and made a huge mess, but it hasn't happened again. My second order was lost by DHL and I had to call and complain, but my order was reshipped same day.

MESS FREE PERIOD?!

I use to wear tampons and a panty liner for my periods, and stopped using pads because UN-SAN-ITARY! Tampons are easy to use but can be scary to leave in at night to sleep...but once I tried FLEX FIT it was a dream to sleep comfortably, knowing I won’t leak! I love using and glad I switched to FLEX FITS. I did try having sex with it in, my partner said he could feel it and it hurt to go deep. I did leak on him but we aren’t afraid of a little mess. TMI!!! It did prevent having him covered in blood like a crime scene. So that’s a pro! I love the fact that I can work out, sleep, and shower with it on without a worry! A MUST HAVE!!!

I’m so bummed I waited so long

I have seen the flex discs on instagram and other places for maybe a year or two now...? It was intriguing but seemed too “scary” to try (because all I could imagine was something getting stuck up inside me forever). I finally bought them during my last target run, kind of as a last ditch experiment. I’m 30 and I have had 3 kids and tampons just don’t seem to work as well as they used to. I didn’t expect it to be prefect on my first try bc I was new etc etc. Well I tried it for the first time during my next period and it was PERFECT! I mean literally perfect. No leaking, super easy to put in/take out and completely comfortable. I’m just upset I didn’t take the plunge and try it out when I first saw them. I’ll never go back to tampons.

I love this product !!

I used this product for the first time , and I literally love it .. it really works .. I had fewer craps , less mess .. I can wear whatever I want to. I really am glad I found this. I was nervous at first. Just the thought of it and the process .. with putting it in, And removing it. But I can say it was a great choice and I would recommend. For those who want to be mess free, less pressure for cramps , just to be happy and pain free. !

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.
