Why you’ll love Flex Disc

Designed for comfort

The rim's ComfortSeal™ technology warms and forms to your body for a
personal fit that keeps you comfy during exercise, sleep, sex and more.

Body-safe materials

No BPA, phthalates, or natural rubber latex. Only 100% medical-grade
polymers that don't host toxic bacteria or disrupt your vagina's natural
pH balance.

Fewer cramps

Because it sits in the vaginal fornix instead of the canal, 64% of Flex Disc users report fewer cramps while using the disc.

12-hour wear

The catch collects five times more blood than a super tampon AKA you can spend less time in the bathroom and more time living your life.

Awesome!
It is weird to figure out how to use one at first, but once you get it you'll love it. Minimal leakage, and intimacy really is mess free!!

Helped my cramps!
I have endometriosis and after I started using the discs, it actually HELPED my cramps! It's cleaner than tampons/pads/period underwear. Reduces risk for TTS. Can hold up to 5+ super tampons. Can be worn while sleeping, swimming and...... Sex. I'm never using anything else besides these. Thank you

Life changing
These are a game changer. I literally tell everyone about them. The only disappointment is that they no longer work since giving birth! I haven’t figured out if I need to find a company that makes a larger size or if things are just different down there now. But, if you haven had kids, and even if you have - these are worth a try!

REALLY MESS-FREE during sex
I've been using these for the last three months and I was already very happy. It wasn't until my last period that I got to test them during sex, I was skeptical but I ended up super impressed, they are really mess-free! It was super comfortable as well, as if wasn't on my period at all. You can tell these were designed by a woman, amazing, thank you!

Can’t wait to try
Giving 5 stars before I’ve even tried it because all the 1 star reviews are from people who haven’t tried the product and only hate the ads because they are uneducated and hold toxic viewpoints on the natural events that happen to women’s bodies.
Yes, some people can and do enjoy sex on their period
Yes, you can actually put your fingers into your vagina
Yes, you can actually exit or skip an ad you don’t want to have to see
Yes, women have periods and no it is not disgusting or evil or dirty that we menstruate
So thank you for making an insightful and informative advertisement and creating a product to help us through a natural but uncomfortable time
