Keep your cup and body fresh AF no matter where you go
Your BFFs will want in on this, too

The Flex Cup Starter Kit has everything you need for a clean, sustainable cycle month after month.

Included in the kit:

Flex Cup, the only menstrual cup in the world that can be removed like a tampon, lasts for years (so you can save moola and the planet), and gives you 12-hour protection day in and day out.

Clean your Flex Cup with the Flex Foaming Cup Wash to keep things foamy and fresh without the use of harsh chemicals. It’s pH-balanced, gyno-recommended, and safe for use on your entire body (intimate parts included).

And, when you’re out and about and your cup wash is nowhere to be found, Flex Biodegradable Wipes have your back. Use these to give your cup a good wipedown before reinserting and getting back to the party. They can also be used safely on your entire body, and to keep your hands and intimate parts clean when swapping out other menstrual products, such as Flex Disc.

Perfect Fit Guarantee. We’re determined to get your size right. If yours doesn't fit, we'll switch it out for another size.

Triple threat: Face and body need freshening? Go for it. Swap out a menstrual product? You bet. Clean your cup on-the-go? Absolutely. Our wipes are designed to be used in more ways than one (but grab a freshie each time plz).
Recommended by OB/GYNs: With a doctor-recommended formula that is safe for both intimate parts and sensitive skin, expect a round of applause at your next appointment.

Flex Cup

Insert - Wash your hands and the FLEX Cup for 20 seconds. Press the sides of the cup together and then fold it in half again forming a tight ‘U’ shape. OR place a finger on the top rim of the cup and press it down into the center making the top smaller for insertion. Get in a comfortable position, relax your vaginal muscles, insert the FLEX Cup into your vagina, sliding it up and back toward your tailbone (not straight up).
Wear it for up to 12 hours.
Remove - Simply pull the ReleaseRing™ to break the seal and remove. The ReleaseRing™ pulls the top of the cup in to break the seal and help prevent spillage during removal. Before using or reusing, remove the ReleaseRing™ and thoroughly wash the cup for 20 seconds with warm water.

Wash

Rinse silicone menstrual cup with cold water (if using Flex Cup™, unthread the pull-tab first).
Wash cup in warm water with a few generous pumps of Flex Foaming Cup Wash.
Thoroughly clean the cup, especially the air holes at the top.
Rinse well with warm water.
Allow the cup to dry before reinserting.

Wipes

Gently wipe wherever needed.
For menstrual cups, wipe all surfaces and allow to dry before reinserting.
Flush product down the toilet to dispose, or toss in the trash.

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.
