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

sits somewhere different.

Unlike tampons and menstrual cups, FLEX sits just past the vaginal canal in the same place as a diaphragm and can't be felt at all once in place.

Wear it for 12 hours.

The best thing about FLEX is that you can wear it comfortably for 12 hours so you can live your best life, even on your period.

Pro tip: Avoid leaks

If FLEX is placed correctly, leaking should be minimum. Until you get the hang of putting it in, you may want to wear a pad or liner just in case.

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.

Pro tip: Mess-free removal

On light days, you shouldn't have any problems with messy removal. On heavy days, many women choose to remove FLEX in the shower until they get the hang of it. That's the beauty of 12-hour wear. You can work around what's convenient for you.

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.
