Not all cups are created equal.

Considering the switch to menstrual cups? Our custom pull-tab and game-changing tech make your decision one you'll only have to make once.

Welcome to the period cup convo, we're happy you're here!

Maybe you've heard of menstrual cups before. Maybe you just discovered them after a frantic Google search for better period products and now you're wondering WTF you've gotten yourself into.

No need to stress, we've got all the important deets about your new BFF.

Cups work differently than tampons.

They collect period blood vs. absorbing it. This means less cramping and more freedom.

Leaks take a back seat.

Most menstrual cups keep you covered for around 12 hours, so you no longer have to worry about urgent trips to the bathroom to check for leaks. Guess it's finally time to toss those period panties.

They make Mother Earth happy.

Menstrual cups are 100% sustainable. They are zero waste and last for years. Cheers to that. 🥂

How to use
Title Logo

Fold it

Take your cup and fold it in half so that the lips touch together. Then, slowly bend the cup in half again lengthwise.

Title Logo

Insert it

Stand with one leg up, sit on the toilet, or squat like it's hot. Then slide the cup up and back toward your tailbone. Ta-da! You did it. Check to make sure the cup is in the right place by inserting a finger into your vagina and running it between the cup and your vaginal wall. This will create space for the cup to open fully.

Title Logo

Wear it for 12 hours

Take swim class, jump from a high dive, present to the board with confidence, go where the wind takes you - whatever. We've got you covered for up to 12 hours.

Title Logo

Remove and wash it

Our revolutionary pull-tab makes removal a breeze. Give it a gentle pull to release the seal. Pull FLEX Cup free from your vagina with one hand and catch it with the other (holding it upright). Empty the contents into the toilet. Then wash the cup for 20 seconds with soap and warm water.

Try FLEX with some liners at first.

Sometimes you just feel better with a little backup. FLEX plus liners would be a great combination for you while you transition to FLEX to help guard against leaks until you get the hang of positioning FLEX.
