WIREOPTIM flexFIBER cotton is 100% organic, unbleached, and pesticide-free. Long organic multi-fiber cotton strands are carefully electo-cleaned and bound by a shoe lace style aglet in order to offer the easiest installation in your application. These fibers are not compressed, and are specially manufactured to offer excellent fluid absorption. Both the 3mm and 6mm variants are crafted to fit perfectly in their respective diameter applications.
I personally enjoyed the lace style cotton, while I thought from the picture that the thin end would have some sort of plastic coating, I found it didn't but that didn't make it any less easier to use. Beyond that, it's exactly what it says!
The usable cotton length is 60mm, and actually can longer because there is no heat shrink shoelace to cut off. The compressed lace end can be fluffed for more usable length. I have sharp-tip tweezers, which make a difference here for fluffing without thinning. One flexFiber usable length so far was actually 70mm, not counting the compressed lace part. My dual coils are usually 30mm each at most, so I can wick both coils with one flexFIBER. Generally no need to fluff because the strands are already fluffy. They wick very well while priming and throughout use. They are quite fluffy, so a very few strands may need to be pulled if your 3mm are a tight, true 3mm, and more will likely have to be pulled for 2.5mm coils. I haven't tried them in larger diameter coils, but they may work well in 3.5mm, though I question 4mm. Glad I decided to try flexFIBER and I will be back for more. Thank you, WIREOPTIM!

Super easy to wick. Plenty of length yet barely any waste. Just right. It doesn’t give off a lot of loose cotton and it doesn’t need much fluffing. Any way this is my favorite to wick my device. This company is also great.
I really like this cotton, I have used Bacon Prime for years and still have a couple full boxes, but I ordered some of this for the simplicity and it's fantastic. Unlike other users though if anything I find it to be a little UNDER sized, maybe they aren't using enough cotton lol. I find it's perfect for my 2.5mm coils and I haven't used it on any threes yet.
Really like this product. Although I find for a 3mm inner diameter coil I need to trim a bit of product off so that it moves easily through coil. Picky I know. My second purchase of this product. A great deal when on sale.
Good product, More like 4 or 5mm not 3mm.
I can't tell the difference between this stuff and any other "premium" cotton. One small gripe I have is they are shorter than most other brands. I can normally get two coils done with a single piece but it's not really possible with these. Other than that I'd definitely recommend it. Great price fast shipping and a good product.
I really enjoyed this cotton I have used almost every commercially available cotton from Cloud 9 to KGB they are both very good cotton but the flexfiber n my opinion is the clear winner here flavor comes through extremely clean with no cotton taste that I can pick up on I spend good money on liquid and I feel as though I'm picking up on all the notes within the liquid definitely my new favorite and we'll be ordering multiple boxes and I've been telling all my friends thank you very much WIREOPTIM.
A very easy to use lace that has almost zero break in time. I have tried over 20 lace style cottons and this is my favorite.
Perfect. Absolutely perfect. It's ideal for any coil with an ID of 2mm to 4mm and will fit even smaller if you just narrow it down a little! This wicking cotton is flavorless, sucks up juice unbelievably well, and is just as amazing at releasing said juice when using it. I keep coming back to it and have bags and bags of other "ultra high grade" cotton just sitting around. It's a huge winner!
