Flex™ Condoms︱ Next Generation Condoms Enhanced with Graphene, The World's Thinnest & Strongest Material︱Advanced Sensation︱ Ultra Thin, Flexible, Strong︱Nontoxic, Vegan, Non-GMO︱10 Count

These are clearly high quality condoms and what I would expect from One. They're very thin, to the point that you can even feel the difference through the wrapper (that part was really impressive to me). I also liked the color--it's a translucent black so it's not silly or distracting but is more attractive than "normal" condoms. Now, in terms of use... I loved these condoms. I (vagina-haver) definitely agreed with the package claim that it has something like 85% higher heat transfer than regular condoms. It was super smooth and the lube was great--the perfect amount, felt natural, and didn't leave any weird-feeling residue afterward. I could feel the difference between using these and condomless sex, but just barely and I probably wouldn't have noticed if I hadn't thought about it. According to my partner (penis-haver), sensation was about 50% more than regular condoms and he also thought the heat transfer was fantastic. It fit well, no slipping, and all in all was just a great condom. Would definitely make this my go-to!

Feel great, fit snug

They feel like almost nothing is there, but I am only giving 4 stars because if you are on the thicker side, they are very tight.

These are great, and I recommend them without qualification--they've become my go-to. Like other top options in the realm of condoms, the other two being Okamoto 004 and Lelo Hex, these feel suspiciously like they "might have fallen off", which is why I appreciate them all being quite snug in their sizing. One Flex Condoms, like the 004 and Hex, are so thin and flexible that this doesn't prove to be a problem, as they are incredibly flexible and reliably strong. Heat transfer is excellent; they come well-lubed, and in contrast to the other two competitors, the price is VERY right when you buy the 36-count package (though shipping is epically slow). Another real positive is that the ONE wrappers are round and a bit more sturdy, holding up in your pocket or bag a lot better than any other option I've found.

Absolutely terrible product, they have absolutely not durability and rip extremely easily

It’s a pretty big tube for ten tiny condoms. The next aggravating thing is instructions that tell you about how much lube you need to use before you put it on and after you put it on. And guess what- besides the big tube and the big price and the big promises, there was none in it. Not that I expected it, but if it is actually mandatory as per the instructions…

I’m thrilled to share my glowing review of these condoms! It’s not every day you come across a product that truly delivers on its promises of both comfort and subtlety. These condoms are so remarkably thin, it’s easy to forget you’re wearing them at all, yet they offer the protection and reliability you need. The comfort factor is through the roof—no pinching, no compromise, just a perfect fit that moves with you. It’s the kind of product that enhances the experience without making its presence known, which is exactly what you want when using it. For anyone seeking a balance of thinness and comfort without compromising on quality, these condoms are a game-changer. They’ve certainly earned a resounding endorsement from both of us!

Amazing feels like nothing is there

They still significantly reduce the amount of sensations and they are a condom, but these are the most sensitive ones I have used.
