This cotton is specially made for the Wotofo Profile RDA, to fit within the mesh coils. It's 6mm in diameter, so we would not recommend it for general use outside of the Profile, as you'll be wasting quite a bit to fit this in a 3mm coil.
Xfiber is a brand new style from Wotofo, that has been electro-cleaned for even more purity of flavour than before! With longer fibers for even better absorption and excellent retention, you'll be loving your Profile, Unity or anything else you can fit 6mm of goodness through!
What's in the box:
1 x 10 pack of 6mm Wotofo Xfiber Cotton for the Profile
