I’m excited to share another new reusable menstrual disc option in this Flex disc review. You may already be a fan of the Flex disposable disc, a black-rimmed plastic disc modeled after the original and first menstrual disc, the Instead Softcup (SoftDisc.)
Now, Flex has a reusable, earth-friendly version. The Flex reusable menstrual disc is made of silicone, so it will last many years, and it’s the firmest reusable disc available.
If you’re new to reusable menstrual discs, check out Period Nirvana’s “how to use a menstrual disc” guides. The basics? You fold a menstrual disc longways and insert it into the vagina.
Your pubic bone holds it in place in an area called the vaginal fornix. This is a “one-size-fits-most” area. After 12 hours, or once your disc needs to be emptied, you’ll remove it over a toilet, dump the contents, wash it, and reinsert it.
Features of the Flex Reusable Menstrual Disc
- Same size as Flex disposable disc: “one-size-fits-most” 69 mm diameter
- Reusable for up to 10 years
- Safe to wear up to 12 hours at a time
- Internal notch for a slimmer fold and easier insertion
- 70 ml capacity
- Firmness rating of 4.5, making it the firmest reusable menstrual disc
- Made of durable, easy-to-clean silicone
Overall Design of the Flex Reusable Menstrual Disc
Flex Reusable Menstrual Disc is as close to the disposable Flex disc as possible, with a few exceptions. This may have been intentional or because the reusable version is made of silicone.
The brand has kept the same rim size of 69 mm for the Flex reusable menstrual disc. The silicone basket (the part of the disc that holds period blood) is extremely thin, similar to the plastic Flex basket. But because it’s made of silicone, the Flex reusable disc doesn’t have a crinkly basket like the disposable version.
How to Insert the Flex Reusable Disc
Inside the rim, there is one small notch. This design choice makes the tip of the Flex reusable disc narrower. That, plus the firmer rim, will make it easy to insert. Center the notch, then fold the disc. Insert the disc with the notch side entering your body first.
How Firm Is the Flex Reusable Menstrual Disc?
The Flex reusable disc is a 4.5 in firmness. It’s slightly less firm than the disposable Flex disc, which is the firmest menstrual disc, at a 5 on the Period Nirvana firmness rating scale.
In truth, the disposable Flex disc is even firmer than a 5 because it’s made of plastic. It would be hard to get a silicone disc to be as firm as a plastic disc, but truth be told, maybe Flex would rather it be less firm. Some people complain about the firmness of the disposable Flex disc, but others like the firmness of plastic discs over reusable ones.
The silicone of Flex reusable menstrual disc molds to your body better than the plastic Flex discs, which tend to hold their shape more. The slightly more bendable silicone of the Flex reusable disc may mean that it gives you more of a leakproof, body-conforming fit than the plastic variety.
Flex Reusable Disc Review: My Personal Experience
As a reusable period product advocate, I don’t love that Flex gives disposable discs as gifts with each “sustainable” period product purchase. There doesn’t seem to be a package that comes without them. While I appreciate the features and design of the Flex reusable disc, it was definitely a moral dilemma to bring it to my period store Period.Shop.
Aside from that, I spent most of one menstrual cycle with the Flex disc reusable version and had a positive experience. Insertion was easy; I was able to use a single hand to fold, insert, and tuck the disc. I don’t have trouble inserting other discs, but if you’ve had trouble in the past, this one should be easier.
When I filmed my review, I forgot to mention that I had one minor leak. It was so minor that I forgot it happened. I’m guessing that it was a “residual leak” of blood that traveled down the walls of the vagina after auto-dumping.
I was a bit surprised how often I found this Flex disc auto-dumping, considering how firm it was. I don’t mind the experience, but I expected fewer instances.

Removing the Flex reusable disc is a more involved process than some of the newer menstrual discs that have added “removal aids.” I sometimes needed to do a fair amount of digging to locate the rim from behind my pubic bone. Removal wasn’t super messy (likely due to how often I was auto-dumping), but it was not mess-free.
For wear and comfort, Flex disc’s reusable option was perfect for me. Even though it’s firmer than my favorite disc, Hello Disc, I didn’t experience any bladder pressure. But in the end, I wouldn’t select it over my favorite because I prefer the ease of removal and no-mess experience of the Hello Disc.
