Flex Disc sits somewhere different

Period freedom is here

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.

Up to 12-hour wear during sleep, exercise, swimming, and more

Mess-free period sex because your vaginal canal is free from obstruction

Reduces cramps in up to 60% of users because it doesn't apply pressure to the vaginal wall

Not linked to TSS and made from 100% medical-grade polymers

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

How it works step PINCH


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.

How it works step INSERT


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

How it works step WEAR


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.

How it works step REMOVE


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.

How it works step DISPOSE


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.

Flex Disc FAQs

How do I insert Flex Disc?

Finding a position that works for your body is essential for proper disc insertion. Some users stand with a leg propped up, some sit on a toilet with their feet propped up on a stand, some squat all the way toward the floor.

Once in position, pinch the disc and push it back into your vaginal canal as if it’s pointed to the floor. When you can no longer pinch it, use your thumb or index finger to push it back even further, so it's propped up behind the pubic bone. Then, you're set! Some people will do squats or kegels to make sure it's settled into place.

Does Flex Disc really work during sex?

Yep! Because Flex Disc sits the vaginal fornix, it leaves the vaginal canal unobstructed—which means sex is on the table all month long. As long as the disc is inserted properly, neither you nor your partner should be able to feel it. However, if your partner (or toy!) is particularly large, there may be some contact with the disc. This shouldn't cause any discomfort and the disc should stay in place.

Will it leak while going to the bathroom?

It might. When you go to the bathroom, the muscles relax and this can cause the disc to shift. If it empties a little, that's totally normal and nothing to worry about. Simply push the disc back into place with a clean finger when you're done. Users with heavy flows can also use this to their advantage to empty the disc mid-wear.
