“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.”

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.

These are legit!

Wow! What a find! I have always been a pad/tampon person. The idea of a reusable anything grosses me out, so when I saw these flex discs AND heard I could have sex without the mess, I had to try them. I am SO glad I did. These things works wonders. Easy to insert and easy to get out, I have had marathon sessions with the bf without any leaks or smells escaping. They are a little messy upon removal until you get the hang of it, but it's worth it and they last a lot longer than a single tampon. I also noticed that upon insertion I had some very mild cramping for about 10 minutes, but after that absolutely ZERO additional cramping. Dare I say these are a miracle? Either way I am converted and will never gp back to old school tampons.

My unicorn

Finally after trying so many other cups that were miserable and beyond frustrating to figure out or wear ... I've found my unicorn. First try and I got it in place and even had sex with it in and NO LEAKING. Perfect product for me and my body. Just to add some info: I'm 40 and I've had 2 children vaginal births.

I'm never going back to pads and tampons!

I can't even tell I am wearing this, I've never used this type of period product and after wearing it on my heavy day with no problems I'm sold!

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.
