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

Why Flex®?

Flex products collect fluid instead of absorbing like pads or tampons, reducing bacteria growth and risk of TSS. They hold as much as 3 super tampons.

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.

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.

Flex Cup FAQs

Why choose Flex Cup?

Flex Cup is the most comfortable and easiest to use cup on the market making it the #1 cup for beginners. Not only is it sustainable and safe to wear for up to 12 hours but users can feel confident in removing the cup. Flex Cup's unique pull-tab makes removal easier than other cups and is also mess-free!

Is it ok to wear Flex Cup with an IUD?

There is a small risk of any internally worn menstrual product getting caught on your IUD - including tampons, menstrual discs, and cups. If you use an IUD, you should be informed about your particular IUDs benefits and risks and consult with your physician.

I have a heavy flow. Will Flex Cup work for me?

Flex Cup is a great option for users with heavy flows. The Slim Fit holds the equivalent of 2 super tampons, while the Full Fit holds the same 3 super tampons’ worth of period blood. The cup's unique pull-tab also makes it easy to remove, empty, and reinsert on the heaviest of days. The majority of our customers have heavy flows - including those with endometriosis and PCOS who swear by Flex Cup!

How does a menstrual cup work?

A menstrual cup sits in the vaginal canal to collect menses, rather than absorbing it. It’s reusable, so one cup replaces your current products for the heaviest to the lightest days of your flow. Since it doesn’t absorb fluid, it leaves your natural lubrication in place, making it much more comfortable to wear. It can be worn for up to 12 hours, is hypoallergenic and does not affect the natural pH of your vagina. The cup is folded to insert, and it opens up inside of you. It creates a seal with the vaginal walls to prevent leaks.
