The 7 Fold:


Fold your cup in half so the lips touch (just like the C fold), then pull down one corner so the lips of the cup form a “7” shape.

FAQs

What's the difference between Flex Cup and other menstrual cups?


We know you've probably been searching the internet for days to find the perfect menstrual cup and you're probably thinking, what's the difference? They're all pretty much the same, right? Not this cup!

Flex Cup can be safely worn for up to 12 hours. It's hypoallergenic and made with medical-grade silicone—but what makes it truly stand out is its super-soft, adjustable pull-tab. The pull-tab threads through a small hole at the base of the cup and attaches to the inner rim (at the top). When you pull down on the pull-tab, it collapses the side of the cup inwards, breaking the suction seal for you. 

Wait, don’t other cups have a stem or “pull-tab,” too? Sure—but those stems are nothing more than a guide to help you find the base of your cup. If you tried to pull down on a traditional cup’s stem without first breaking the seal, you could put your vagina and cervix at risk for suction-related injury or discomfort. 

Imagine trying to get a suction cup off your shower wall by pulling straight back: probably not gonna work, right? You have to get up under that suction cup by peeling one side away from the wall. Same idea with a menstrual cup! Typically, you have to manually grip the base of your cup with a finger and thumb in order to break the seal before you pull it out. 

With Flex Cup, you can skip that step and use the pull-tab the same way you’d use a tampon string. This design makes Flex Cup beginner-friendly, more accessible for those with disabilities, and perfect for IUD users.

Which Flex Cup size is right for me?


Choosing the right menstrual size for your body may take some trial and error—but that’s why Flex Cup comes with our Perfect Fit Guarantee

If you’re a first-time cup user, we recommend starting with the Flex Cup Size 01 (formerly Slim Fit). If you’re a seasoned period cup pro, or if you’ve given birth vaginally 2+ times, we recommend Flex Cup Size 02 (formerly Full Fit). For most people, either size will work. It really comes down to choosing the best fit for your comfort and capacity needs. 

Here’s a breakdown of each cup’s dimensions:

Size 01:

  • Diameter: 43 mm

  • Length: 46 mm

  • Holds as much as 2 super tampons

Size 02:

  • Diameter: 46 mm

  • Length: 53 mm

  • Holds as much as 3 super tampons

Not sure which size to pick? Reach out to our Flexperts at 800-931-0882 or email hello@flexfits.com—we’re happy to help! 


How long will Flex Cup last?


With proper care, Flex Cup can last for years—so it’s better for your wallet and the planet. Most long-term cup users choose to replace their cup every two to three years, but it all depends on how well you clean and maintain your cup. Refer to our Flex Cup Cleaning Instructions to learn how to care for your silicone period cup and extend its lifespan. 

If your cup is showing any signs of deterioration, such as powder or film on the cup, severe discoloration, persistent odor, etc.—that means it is time to replace. 

As a reminder, do not use Flex Cup if you have a yeast or bacterial infection. Resume use only once the infection has completely cleared. If Flex Cup was inserted during a yeast or bacterial infection, remove it immediately and dispose of it in the trash.

Will Flex Cup work for a heavy period?


Many of our customers with heavy periods swear by Flex products. Flex Cup is a great option for users with heavy flows. Size 01 holds the equivalent of 2 super tampons, while Size 02 holds the 3 super tampons-worth of period blood. Plus, the cup's adjustable pull-tab makes it easy to remove, empty mid-wear, and reinsert on the heaviest of days.
