Thats what I use.
When I first started to rebuild I ordered 2 rolls (30ga and 28 ga) for my Kafun's. I find that can get a month or two from a microcoil on the
kayfun. So I figure the 2 rolls should last me about 50 years.
I also screwed up the courage to walk into Sally Beauty supply and bought the smallest box of Cellu-Cotton (Rayon) they had, about 25 feet. Changing wicks a couple of times per week I figure that will last about 100 years.
