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.

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

Have period sex without the mess: Flex Disc leaves your vaginal canal 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.


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.

    Very happy

    I was really unsure about menstrual discs and there’s definitely a learning curve. But overall, it was pretty great. I’ve had a very heavy period since having a baby. Plus, I’m a home hospice nurse so I’m on the road a lot and was always worried about leaking or finding a bathroom to change my pad or tampon. With the disc, I didn’t have to think about it all day, and only used 2 in 24 hours. It was pretty amazing. My only gripe was the removal- it’s extremely messy during the heavier days and if you’re not prepared for it, it’s jarring. I got better at it with each change, but my hands got a little messy every time. Overall though, this made my most recent period a much easier experience!

    Best ever, highly recommend

    This product was amazing to use for my period. When you use it for the first time, wear a panty liner or thin pad for extra protection, I can't imagine going back to pads already and it's my first time! Insertion is very easy and you will never feel it, you will have to be ready to wipe your hands with something snd then wash them after removal, otherwise ZERO worries. I recommend this for anyone using this product on my period was amazing. Less stress more fun. Thank you so much to flex for making my period so much better! This dreaded week isn't so bad!

    One reason only

    I’m going on a romantic trip with my boyfriend and my dreaded Aunt Flo was supposed to come earlier in the week and be done before we left for the trip could I be so lucky… no but none the less bought the disk to try I’ve “practiced with it the last two days seems to do fairly well had a decent leak the first night of wear but other than that seems decent! It’ll get the real test this weekend really hoping it holds up to the whole mess free sex thing!

    Game Changer

    I adore the disc! This has been my first period using these and my life is forever changed! The video and instructions were so clear, it took a little bit of me finding a comfortable way to insert it but I found that the less scared you are, the easier the insertion since you tend to tense up down there when nervous. Taking it out was a little scary, however very easy! I have had no leakage (and I have a very heavy flow), and I absolutely do not feel it at all throughout my day at uni, work, sleep, and fun time😉I tried this product before buying the reusable one, but I’ll definitely be getting the reusable one next!

    What was I scared of?

    I finally ordered the reusable discs a few months ago after almost a year (at least!) of contemplating making the purchase. Yesterday I tried them for the first time and wish I had done this years ago. I had zero issues inserting it (it's just as easy as a tampon), zero issues "dumping" it, and zero issues changing it (although it was definitely a little messy, I'm sure I'll get better at it the more I use them!). I worked out today on my heaviest flow day and had no leakage. I had ordered the disposables just in case I didn't like them but just ordered the reusable discs to use moving forward. Best purchase I've made in ages.
