New 100 % Rayon Fiber Cellucotton Vape Wick - VC Worx (.5 Meter) Strand.

The naturally soft 100% Rayon fibers are blended into a fluffy, absorbent coil.

As with all wicking materials, the first saturation is most important. Let your e juice completely absorb into the wick before firing up.  Once you get past the "break in period" which is usually around 10 good drags, and re-saturation, then the cotton will come alive with flavor and vapor.  The more you vape it the better it gets.  Just don't let it get dry or burn cause you might have a burnt taste.
