Flex Cup

Flex Cup is a reusable menstrual cup made from body-safe, medical-grade silicone, and the only cup with an adjustable, patented pull-tab that makes removal as easy as a tampon. That single feature removes the biggest barrier for beginners switching from tampons to a cup. Wear it for up to 12 hours of leak protection, day or night. One cup lasts up to 10 years, replacing years of disposable period products. Comfortable, low-maintenance, and kinder to your wallet and the planet.

Comes with a carrying pouch, plus 2 free single-use Flex Discs; FSA & HSA eligible.

Size 1: Capacity of 2 super tampons (22mL) and for first-time menstrual cup users and pros with light or heavy flows. 43mm x 46mm.

Size 2: Capacity of 3 super tampons (30mL) and for experienced menstrual cup users who prefer a larger size or who have had 2+ vaginal births. 46mm x 53mm.

    Best Menstrual Cup I've Ever Had

    I've only had one other menstrual cup in my life and this design is much more effective for the pull out method. It pulls the wall away so the suction doesn't hurt as much when you pull it out. I love using a menstrual cup as a busy woman. Now, all I have to do is put it in first thing in the morning, and clean and replace it at night before bed. What a life changer!

    So much easier than I thought

    I was gifted this cup through a Womxn's Center event at my university and it has been a holy grail. I have always been intimidated by cups but really wanted one because I'm tired of spending money on pads and tampons, and I'm also afraid of the longterm effects of bleached cotton on my body. This cup took a bit of a learning curve (couldn't get it on one cycle so I had to wait til the next), but once I got it, I could just use it and forget about it. I love my Flex Cup!

    Cup tab

    Why when I have it in little bit blood comes out? Is it because of the pulling tab or what

    6 years and 100s saved

    Bought my first one in 2018 and am just replacing it today in 2026. I originally bought it because the suction on other cups was so horrible and the pull portion too short. This has been a life saver and saved me what I can imagine is hundreds, if not thousands of dollars in pads. Periods just feel so much more manageable. 1000% happy to buy a replacement.
