Rinse your silicone period cup or disc with cold water. If you’re using Flex Cup, unthread the pull-tab first. With a generous pump of Flex Foaming Cleanser and some warm water, thoroughly clean the entire cup or disc (if using Flex Cup, give some extra love to the air holes at the top). Rinse well with warm water and allow the cup or disc to dry before reinserting.

Make sure to remove, empty, and clean your reusable menstrual cup or disc at least once every 12 hours.  Flex Foaming Cleanser is designed to be used on all silicone period products.

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.

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

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

SIZE 01	SIZE 02
Capacity of 2 super tampons (22mL)	Capacity of 3 super tampons (30mL)
For first-time menstrual cup users and pros with light or heavy flows	For experienced menstrual cup users who prefer a larger size and those who've had 2+ vaginal births

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