Well the verdict is its good.. New local cheap source to try. Good for people that just want to try rayon or as a primary source.
I've got kotex U sleek in the black box. Labeled 100% rayon, elemental chlorine free bleached. (Safe), rayon/ poly string, package.. Any of these labeled similarly should work.
Its inexpensive and readily available. One ends up being quite a bit probably 10-20 wicks depending. It reminds me, looks the same as the pharmaceutical rayon. Same dry look and feel, I think its essentially the same. Its vaping very good. Neutral taste. This is out of the box clean.
There is a layer of wrapping around the outside you remove and then unroll it.
From here on I will refer to it as KU Rayon
