Will it fit?
Flex Reusable Disc was designed to fit most vaginas. When you pinch the disc in half to insert, it’s about the same size as a tampon. It sits comfortably in the vaginal fornix—at the back of the vaginal canal, just beneath the cervix—and collects, rather than absorbs, your period.
Flex Reusable Disc customer reviews
- MNMi N.1 week agoRated 5 out of 5 starsFeel like nothing inside me
I used period cups for a long time, the kind looks like a reverse bell with a tip to pull out. The tip gave me an uncomfortable feeling that made me want to use it for just two heavy days. I bought the Flex disc with a skeptical thought, that’s somehow I might feel the thing a bit. But I was wrong, completely free from feeling anything inside. Im so happy with my purchase and had to buy them for my sisters too.

I absolutely LOVE this little thing!!! Lol
I have been bleeding almost non stop for 9 months. I was so sick of buying tampons. I came across FlexDisc and gave it a shot and will never go back to tampons. Yeah you have to get used to changing out a cup, but once you get comfortable with your body and that aspect of it, this FlexDisc is TRULY a God-Send! I abso-freakin-purely LOVE it. I think it’s the best thing since chocolate.

I had my first baby in 2024 and I did NOT realize how much my pelvic floor would be impacted. I can’t use cups anymore!! I’ve spent a few cycles now crying over it because using anything but a cup was so painful and my period was MISERABLE!
I came across the flex disc and decided I had to try it because I was desperate. This is my first cycle actually being able to use it and OH. MY. GOSH!!! This disc just saved my mental health when my period comes around, and I LOVE that I can have sex with it?!?! Like what!!!!! Try a disc, ladies!! It’s amazing!

Holy moly, this thing is MAGIC. I've tried cups before and could never get them to work properly and I'm tired of paying for tampons. The fact that Flex doesn't rely on suction was a big selling point for me. I'm currently using it for the first time and I'm just amazed. The self-empty actually works, I haven't had any leaks, and it's so easy to put in and take out. I highly recommend it!

I used the flex cup for several years and thought switching from tampons to a cup was lifechanging. But after trying the flex disc, I'm never going back to anything else. I don't feel it at all, it works even better than a cup, and has saved me so much money and waste from no longer needing to keep getting tampons.
My only "complaint" would be that I wish they offered the disc in black like the flex cup because it stains very quickly. But that's just a personal preference and I can't recommend this product highly enough.

Frequently Asked Questions
Flex Reusable Disc is a body-safe and sustainable menstrual disc that provides all-day comfort and a high capacity, holding as much as 6+ super tampons-worth (70 mL) of fluid. It was thoughtfully engineered to be as easy to insert and remove as our best-selling disposable Flex Disc—but it’s 100% reusable and lasts for years.
Flex Reusable Disc features two new technologies for easy insertion and removal: Made with dual silicone construction, the disc has an ultra-soft, thin catch and a sturdy rim for non-slip removal, while its patented insertion notch creates a narrow point at one end when the disc is pinched for easier placement.
Like Flex Disc, the Reusable Disc is worn in the vaginal fornix. This means the vaginal canal is left unobstructed, so you can enjoy all the mess-free period sex™ your heart desires. Sleep in, swim, go for a run, live your life: Flex Reusable Disc provides 12 hours of uninterrupted leak protection and comfortable wear. You might even forget you’re on your period.Flex Reusable Disc: Great for your wallet. Even better for the planet.
The lifespan of the Flex Reusable Disc varies depending on cleaning and care, but it can last for years. As a general rule of thumb, we recommend replacing your disc every two to three years, or as soon as it begins to show any signs of deterioration (such as powder or film, severe discoloration, persistent odor, etc). Refer to our Reusable Disc Cleaning Instructions to learn how to care for your silicone disc and extend its lifespan.
As a reminder, do not use Flex Reusable Disc if you have a yeast or bacterial infection. Resume use only once the infection has completely cleared. If Flex Reusable Disc was inserted during a yeast or bacterial infection, remove it immediately and dispose of it in the trash.
Taking good care of your Flex Reusable Disc will help to extend its lifespan and keep it clean and fresh for years.
Here’s what we recommend: During your period, remove, empty, and clean your Reusable Disc at least once every 12 hours. Start with clean hands and grab some mild soap or cleanser (like Flex Foaming Cleanser).
Rinse your disc in cool water first—this will help prevent odor and staining of the medical-grade silicone. Then, switch the water to warm and add a few pumps of cleanser. Use your fingers to massage the entire surface of the disc, including both sides of the rim and catch, and then rinse.
Shake off excess water or let the disc air dry before reinserting. If you’re putting your disc away until your next period, make sure it’s completely dry before storing. Store Flex Reusable Disc in a cool, dry place in its included pouch. Never store your disc in an airtight container.
Once every month or so, it’s a good idea to boil your Reusable Disc to sanitize it. Heat a pot of water to boiling on the stove. Place the disc in the water and boil for 10 minutes, keeping an eye on it the entire time and stirring occasionally to make sure the disc does not come in contact with the sides or bottom of the pot (as that could melt the silicone). Remove from the pot and let the disc cool and dry completely before storing.
Remember: Never wear Flex Reusable Disc if you have a yeast infection or other vaginal bacterial infection. If Flex Reusable Disc was inserted during a yeast or bacterial infection, remove it immediately and dispose of it in the trash. Do not attempt to clean and reuse your disc if it was worn during a vaginal infection.
- Wash your hands and clean Flex Reusable Disc using warm water and a mild soap or cleanser.
- Locate the easy insertion notch on the inner rim of the disc. Make sure that the notch is facing up and the catch is situated below the rim, extending downwards. Pinch the disc in half so that the notch creates a leading edge (AKA a narrow point) for insertion that you’ll use to guide the disc into the vaginal canal.
- Choose a position: Either sit on the toilet, squat with knees wide, or put one leg up on the toilet. Relax your pelvic floor and gently separate your labia with your free hand.
- Insert the pinched disc (notched end first) into the vaginal canal, pushing the disc down and back into the fornix, towards your tailbone. Push the disc as far as it can comfortably go. It may feel strange but it shouldn’t hurt.
- Use your thumb or index finger to tuck the front rim of the disc upward and behind your pubic bone. When inserted properly, you should not be able to feel the disc internally (AKA with your vagina).
Mid-wear experience:
- When you first start using the Reusable Disc, it's normal to experience a small amount of leakage. It may take a couple of cycles to get the hang of positioning the disc and figure out how it sits in relation to your unique anatomy.
- Worried your Reusable Disc is getting full? You can empty some of the blood hands-free just by sitting on the toilet. To do so, bear down on your pelvic floor muscles (as if you're trying to poop). This will move the disc forward, just beyond the pubic bone, releasing some of its contents into the toilet. When you're done, use a clean finger to tuck the disc back into place.
- Anytime you go to the bathroom, remember to use a clean finger (or the thumb trick) to make sure your disc is in the proper position, tucked up behind the pubic bone.
How to remove Flex Reusable Disc:
- Wash your hands. Sit on the toilet and relax your pelvic floor muscles.
- Hook your finger (either your thumb, thumbnail-side-up or your index finger, nail-side-down) under the rim of the disc. Pull straight out, keeping the rim parallel to the floor. If needed, help push the disc out by bearing down on your pelvic floor as if you’re trying to poop.
- Empty the contents into the toilet and repeat steps 1-5 to clean and reinsert your Flex Reusable Disc.
