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.

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.

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 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.
