Considering the switch from tampons? Period innovation is here to give you freedom.

Flex Disc sits somewhere different

Unlike other period products that sit in the vaginal canal, Flex Disc sits in the vaginal fornix. Plus, Flex Disc collects fluid rather than absorbing it like a tampon.

“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."


A helpful guide to Flex Disc insertion, wear & removal.



Flex Disc may look big but it’s actually smaller than a tampon when inserted. Start by washing your hands and pinch it in half.

Use a clean finger to push the disc back and down toward the cervix, then tuck it up and behind the pubic bone.



Once the disc is in place, you should be comfortable and unable to feel it. You can wear it safely for up to 12 hours.



To remove, hook a clean finger under the rim of the disc and pull straight out. Keep it parallel to the floor to avoid spillage.



Pour the liquid into the toilet, and wrap the disc in toilet paper (or a Flex Eco Disposal Pouch) before tossing it in the trash.

    How could anyone go back to tampons? These are amazing and I love how they empty themselves when you pee, but never leak in other positions!!! The best!

    The only period solution for me

    I will be devastated if this company ever ends- these have changed my whole period life. I'm obsessed and so thankful for them.

    Love the flex disk!

    I love this product! They are comfortable and you completely forget you are on your period. I have been intimate while wearing it and you never notice it’s there. It did move farther up and scared me just a bit but when I beared down it moved back into place. I did also try the reusable flex disk but I like the single use better!
