Review: Best menstrual cup! - I love this cup! I have used the same menstrual cup for the last 10 years and I am so glad I bought this one. I will say i have tried other cups that I hated and stuck with the cup I had for so long. I wish I had tried this one sooner. I love that the stem is adjustable and that the ring is so flexible and soft. I had to cut the stem of my last cup because it was stiff and it would irritate me. This one doesn’t have that issue. Another pro is that the cup is stiffer, and seems to open inside easier due to this and stays in place. My last positive is the way it breaks the seal. My goodness, the suction can be so uncomfortable when trying to get a cup out. However, the way this cup breaks the suction makes it significantly better! I do think I’ll need to get the larger one as the small one doesn’t seem to hold as much (even though I’ve been using one of similar size). Overall, I highly recommend!!
Review: Honest Review - Hello to all you skeptical potential buyers! Read here for a honest review of the pros and cons! I've been using my cup since Nov 2022. For reference, I'm 24 years old, about 130 lbs, no kids, and have a pretty heavy period. Overall I would give it a 4-5 review and I like it. PROS: 1) Holds 12 plus hours worth of blood if inserted correctly and depending on your flow. I work long 12 plus hour days on the ambulance and typically won't have to change it if I inserted correctly. Makes it nice for long days. 2) Save a lot of money on other products. I haven't had to buy tampons or pads in quite a while due to not using them as much. I will occasionally still use tampons when I don't wanna use the cup. I would recommend wearing a pad with the cup until you figure it out. 3) Fairly unnoticeable when inserted correctly. 4) Fairly easy to remove with minor discomfort. The ring makes it so much better to remove compared to other cups and brands. Easy to clean too. CONS: 1) If not inserted correctly it's not comfortable and you will leak. Make sure to wear a pad till you figure it out. It takes a while to figure out how to avoid leaking. 2) Could just be me, but when it's inserted and in place I always feel like I need to pee shortly after peeing. That could be me not being able to empty my bladder fully from the cup. 3) Can be messy.

## Features

- UNIQUE PULL-TAB DESIGN. Don’t fear your cup being stuck. Removal is as easy as pulling a tampon string. Experience the only cup in the world with a patented pull-tab for beginner-friendly removal. Simply pull on the stem to effortlessly break the cup’s seal. So easy, you already know how to do it.
- BODY-SAFE. Flex Cup is made in the USA using 100% medical-grade silicone. Our period cups are FDA registered, hypoallergenic, and are not made with BPA, phthalates, or natural rubber latex. Flex products won’t disrupt your vaginal pH and have not been linked with TSS.
- RELIABLE. Be worry-free with up to 12 hours of period protection. Never rush to the bathroom to change your tampon or pad again, whether you’re sleeping, swimming, working or in class. Flex Cup Size 01 (formerly Slim Fit) holds as much fluid as 2 super tampons.
- BELOVED BY EVERY BODY. Flex Cup was designed for beginners who prefer a cup with the easiest removal. Flex Cup Starter Kits come with a Flex Cup, two disposable Flex Discs, and a convenient carrying pouch.
- SUSTAINABLE. Flex Cup is 100% reusable and lasts for years with proper care. To clean your Flex Cup, simply empty your cup, rinse with cool water, apply a mild soap or cleanser (like Flex Foaming Cleanser), lather, and rinse again with warm water. Let your cup air dry and store in its pouch until next time.

### ⭐⭐⭐⭐⭐ Love it!
*by M***E on May 30, 2026*

I am in my 40s and was always intimidated by cups. I hate tampons though and wanted to try something different. I researched different types of cups and decided on flex bc of the loop. I watched a few videos and took the leap and I'm so glad I did! I really liked this design. Very little leakage and easy enough to get in and out. I'm so glad I found this product and decided to try before the summer!
