FLEX is a disposable, single use menstrual product that can be worn safely for up to 12 hours.
Once inside the body, FLEX has an outer edge made of a proprietary blend of medical-grade polymer. This material uses your body heat to warm up to form your natural shape, creating a leak-free seal. The soft center catch collects rather than absorbs your menstrual fluid. The circumference of the edge is made to fit inside the vaginal fornix, covering the cervix, and preventing menstrual fluid from entering the vaginal canal.
Because FLEX does not sit inside of the vaginal canal (like a menstrual cup or tampon), it’s free of obstruction, which makes FLEX extremely comfortable. This feature also comes in handy if you’d like to try mess-free sex. Cool, right?
If you’ve ever inserted a ring-shaped, insertable birth control or a diaphragm, it is quite similar and just as easy. (But it’s equally important to note that FLEX is not a contraceptive and does not protect against sexually transmitted infections).
If you still have questions, we’re here for you! We’re always available on live chat or at firstname.lastname@example.org. Think of us as your girlfriend on the other side of the bathroom door - we’ll walk you through it just like the first time you learned to use a tampon or pad.
You can wear FLEX for up to 12 hours.
If your flow is especially heavy, you may find that on heavy flow days your changes will be more frequent.
Try FLEX for the first time on a lighter flow day to get used to the fit and amount of menstrual fluid it can hold.
Yes, and many of our customers already use FLEX for their full cycle. FLEX is an alternative to tampons, pads and cups. It can be worn safely up to 12 hours, including overnight.
We have found that on average, most of our customers use 8 FLEX per cycle.
If you’re looking for a larger quantity, we also offer 24 count FLEX packages.
Yes, FLEX is safe to use with an IUD.
But if you use an IUD, you should be informed about your particular IUDs benefits and risks and consult with your physician.
When placed properly, your FLEX should not leak or overflow. It can hold up to 6 teaspoons of fluid (or the equivalent of three super tampons). The average woman menstruates about 3 teaspoons in 24 hours. FLEX must be changed every 12 hours, so the average woman will have only 1.5 teaspoons of fluid inside.
That said, every woman is different. If you’re concerned about it getting too full, we recommend first trying at home at night, on your second or third day, so you can get a sense of how much is in it after 12 hours and adjust how frequently you change it based on your own flow.
Pee, poo, do whatever you gotta do - FLEX will stay out of the way.
FLEX may move a bit when you do these things, so don’t be alarmed if you see a bit of red in the toilet. Use a clean finger to double-check that the upper edge of FLEX is in placed behind your pubic bone, just as you inserted it initially.
REMOVAL & DISPOSAL
When you’re ready to remove FLEX, sit on the toilet and use your finger to feel for outer edge of FLEX. Your finger will be on the clean side of the catch.
Push down on your pelvic muscles like you’re taking a poop (yep, we said that) and hook your finger beneath the edge to pull it straight out from the body, keeping it horizontal to the floor. Use the wrapper it comes in to dispose of your FLEX in the trash.
If visual direction is more your style, check out our how-to page.
FLEX is disposable, but not flushable. FLEX is not meant to be flushed and can cause damage to plumbing. Don’t you do that!
FLEX is not reusable and should be changed every 12 hours.
SIZING, COMFORT, & SAFETY
No, but FLEX is designed to fit most women.
FLEX is the smallest, most comfortable menstrual disc on the market and was designed to fit the vast majority of women, including mothers.
Every woman has a unique internal shape and size. A small percentage of women may find that FLEX does not fit. We’re really bummed if that is the case for you, but know we’re working on bringing additional sizes to market. If that’s your experience, let us know by emailing email@example.com.
And you can always ask your doctor if you’re not sure if FLEX is right for you.
Not if inserted properly.
FLEX works by catching your blood as it comes out of your cervix. Menstrual fluid is collected (similar to a cup) rather than absorbed (like a tampon) making the likelihood of a leak, well, less likely.
You may notice leaking when going to the bathroom, and know that this is normal. When you use the restroom, your muscles tend to “bear down” and can push FLEX out of place. If this happens, fret not.
You can use a clean finger to check that the top of the edge is resting behind your pubic bone and you’re good to go.
You should not be able to feel FLEX at all.
If you can feel it, try pushing FLEX farther back before tucking the front edge behind your pubic bone.
No, FLEX can’t get lost inside of you.
The cervical opening is far too narrow to allow an object to pass through.
If you have trouble removing FLEX, don’t panic. Try sitting on the toilet and bearing down with the pelvic muscles which will push FLEX towards the vaginal canal. Once in the vaginal canal, you will be able to easily hook your finger around the edge and comfortably pull it out.

No, FLEX should not cause cramping or discomfort when placed properly. In fact, you shouldn’t be able to feel it at all.
Unlike a stiff tampon, FLEX is flexible and moves with the contractions of your body, helping to ease or eliminate the pain of cramping.
If you experience discomfort while wearing FLEX, review the instructions here and ensure you have placed FLEX properly.
Yes, FLEX is safe when used as directed.
FLEX is made out of materials that are medical-grade and have been tested for biocompatibility. It’s hypoallergenic, silicone free and made without natural rubber latex. Unlike a tampon, FLEX does not disrupt the PH of your vagina, which can lead to yeast infections or bacterial infections.
FLEX is made in Canada at an FDA registered, ISO Compliant facility.
Products like the Flex have not been linked to promoting growth of the bacterium Staphylococcus Aureus, the bacterium believed to cause Toxic Shock Syndrome (TSS).
Although TSS can occur in men, children and women, it is a disease that mostly affects menstruating women who use tampons. Population studies suggest that the risk of TSS is related to tampon absorbency; the higher the tampon absorbency, the higher the risk of contracting TSS; the lower the absorbency, the lower the risk of TSS. Unlike tampons, Flex is non-absorbent; it holds rather than absorbs menstrual fluid. However, consumer usage of Flex has not been extensive enough to date to quantify the risk of TSS, if any, while using Flex. As a precaution, users must change Flex after 12 hours maximum wear time. TSS is a rare but serious disease that may cause death. The warning signs include a sudden high fever, vomiting, diarrhea, a rash that looks like sunburn, dizziness, fainting or near fainting and muscle aches. TSS can progress rapidly from flu-like symptoms to a serious illness that can be fatal. If you have any of these signs and you are using Flex, remove it and immediately contact your physician for medical care.
If you have ever had Toxic Shock Syndrome (TSS), do not use Flex or any other internally worn product.

We’d be lying if we said we weren’t nervous our first time as well. The good news: we can confidently say that FLEX is the best menstrual product on the market and our customers will back us up on that. Still unsure? Check out our pro tips below.
- If you haven’t read them, start with these simple instructions.
- If you plan on wearing FLEX in place of a tampon, pad or cup, (and we highly recommend you do) try it for the first time on a lighter flow day or at night. This will allow you to get accustomed to the fit and length of time that is comfortable for you to wear it.
- Unlike a tampon which you insert straight up, you want to push FLEX straight back and slightly down.
- If you’re having trouble removing FLEX, try bearing down with your pelvic muscles to push it into the vaginal canal. Then use your finger to grab FLEX and pull straight out.
- It takes time to learn how to ride a bike, make the perfect grilled cheese and use a tampon. FLEX is no different. The more you use it, the easier it will be to insert and remove.
- For a mess-free removal, sit on the toilet, distributing weight evenly on both legs, and slowly pull FLEX straight out. It may take a couple times to practice removing FLEX before really nailing it. Patience, grasshopper.
We love this question. FLEX is similar to a menstrual cup in that it is worn inside the body to collect menses rather than absorb them (like a tampon). However, FLEX is a menstrual disc™ as it differs in design, fit and features.
- FLEX is a single use device and was created to be discarded after each use as a more convenient alternative. Menstrual cups are meant to be rinsed and reused for every cycle.
- Menstrual discs are soft and fully collapsable with a thin membrane center and flexible outer rim; menstrual cups are firm and bell-shaped with a stem
- Menstrual discs are worn in the vaginal fornix, at the base of the cervix; menstrual cups are worn in the vaginal canal
- Menstrual discs can be worn during sexual intercourse; menstrual cups must be removed before vaginal sexual intercourse
- Menstrual discs have one method of insertion and removal; menstrual cups may be folded and inserted in a variety of ways
- Menstrual discs generally have a similar size and shape; menstrual cups come in a variety of shapes and sizes
- Menstrual discs have not been linked to TSS; though rare, menstrual cups have been linked to TSS
- FLEX is made of medical grade polymers that get softer inside of your body; menstrual cups maintain their hardness inside of your body
- FLEX is hypoallergenic, made without silicone or natural rubber latex; most menstrual cups are made of either natural rubber latex or silicone
The Flex Company makes both Softcup & FLEX, which are both menstrual discs. The key difference is in the materials and service FLEX provides customers. FLEX is made with newer technology & materials. FLEX uses your body heat to warm up to form your natural shape, creating a leak-free seal.
FLEX customers have premium access to subscriptions with free shipping, phone, chat and text support.
We’ve also designed our packaging to make for more convenient carrying and disposal.
FLEX is not a contraceptive, does not protect you against sexually transmitted infections and should not be used in place of birth control. FLEX is safe to wear with condoms and could be worn in conjunction with your preferred method(s) of contraception.

Yes! If you’ve been an active subscriber with us for three or more shipments, you are eligible to refer others to Flex.
When you receive at least three shipments of the 8-pack or 24-pack subscription, you become eligible to refer others to Flex. At that time, you will receive two invites for a free 8-pack box that you can send to anyone at anytime by logging in here.
If you continue to be an active subscriber, with every following shipment you will receive another invite. There is a maximum of five free 8 pack gifts that you can have at any one time.
Sort of. You can only have up to five free boxes of FLEX in your account.This does not mean that over the course of your subscription you will only be able to send five invites. It just means that if you accumulate five invites, any additional subscription orders you place afterwards will not earn you another invite. So if you have five invites in total and then earn another invite with your sixth shipment, your number of invites will not increase to six but stay at five. So, send the free boxes to your friends, keep on FLEXing, and we’ll give you more FLEX to gift!
