I just picked up some CelluCotton (rayon) and let me tell you this stuff is better than organic cotton balls. I was originally gonna buy some Koh Gen Doh, but it is almost impossible to find in stock anywhere. I wicked my Russian 91% and Patriot rda with the rayon and this stuff won't stop wicking lol. It gives off the cleanest flavor I have ever tried and there is absolutely no break in period.
