Your period doesn’t have to ruin your big day. Say “I Do” to FLEX, the tampon alternative that will keep you covered from ceremony to honeymoon.
Only $13 for your first box
is a disposable menstrual disc.
The convenience of a tampon, the long wear of a cup, and comfort unlike anything you've ever experienced.
12 Hour Wear
Holds 5 tampons worth of fluid. Enjoy your special day without interruption. No more worrying about staining your dress or missing the perfect photo op from frequent changes.
Relieves cramping
Relieves cramping for 7 of 10 people. Because FLEX sits in the fornix rather than the vaginal canal, it limits the distention in the vagina relieving cramping.
Period Sex? Yes.
Period Sex? Why not? Enjoy mess-free + worry-free sex while on your period. Spend more time enjoying your honeymoon and less time worrying about hiding it from housekeeping.
Less Odor
The DiamondWeaveTM construction of FLEX prevents menses from being exposed to oxygen, naturally eliminating period odor without the use of harmful fragrances, chemicals or dyes
Less Leaks
FLEX's ComfortSealTM design comfortably forms to the shape of your body to create a leak-resistant seal.
OBGYN approved and body friendly.

FLEX is made of a medical-grade polymer used in surgical tools that go inside the body. It is FDA registered, hypoallergenic, BPA & phthalate free and made without natural rubber latex or silicone.
“Flex was designed to solve many of the problems caused by traditional menstrual products. It doesn’t change the vaginal flora reducing the risk of infections and has not been linked to toxic shock syndrome.”

Lauren said,
"I typically don’t do hikes longer than 12 hours. Before FLEX I was constantly worrying about my period while hiking. FLEX was basically life changing because I didn’t have to worry about changing it."
Megsquats said,
"I found this to be 10x more comfortable than a cup while I was lifting. The flexibility of FLEX makes it so that it’s way more comfortable. I completely switched, I’ll never buy a tampon again. I 100% recommend for any deadlifts..."
Kristin said,
"When you have a light flow, a tampon is really uncomfortable. I thought FLEX was great because it just slides in and out and there’s none of that horrible cotton pull.”
Using 
is easy.
Unlike tampons and menstrual cups which plug the vaginal canal, FLEX sits just past the vaginal canal and can’t be felt at all once in place.
Inserting FLEX
Slide FLEX into your vaginal canal. Push back and down toward your cervix as far as it will comfortably go (typically the length of your index finger).
Use your finger to tuck the front edge up behind your pubic bone, so it rests diagonally.
Removing FLEX
Hook your finger under the front edge. Pull straight out, keeping your FLEX parallel to the floor.
Place your used FLEX back in its wrapper. Discard in the trash.
Have the most comfortable period of your life delivered to your doorstep.
Forget about being caught empty handed and running to the store. FLEX ships you the product you need, exactly when you need it.

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.
