Fiber and Cotton
There are different types of fiber and cotton used in the making of e-cigarette coils. The cotton puff and the Japanese are the easiest to work with and the cheapest of the range, whereas the Cotton Bacon V2 or the Fiber Freaks are more elaborate materials and provide a far superior capillarity.
The Fiber Freaks has been subject to lengthy research and testing from the French manufacturer in order to develop a cellulose-based fiber that does not have any residual taste once it is set up. Available as the Cotton Blend and the Original, it is a resounding success among vapers, especially those who use e-liquids with a lot of vegetable glycerin.
