Quick, easy, great quality, what more do you need? Seems to be a brushed muji cotton, so works very well..as others have said, better suited to 2.5mm coils. If you're a MTL vaper, they're perfect!
This cotton is brilliant as a second to my other number 1 cotton brand when I’m being lazy to work out cotton thickness. This is best used with 2.5mm coils personally I don’t believe there’s enough cotton for bigger coils
