And I will start by saying its a huge improvement over the tube tank by volcano, imo. I've also read about silica and although I don't find it anywhere near as bad as the stuff in cigarettes, I still want to rebuild my heads... But I've yet to find a direct link to the materials... I like the idea of cotton and ssmesh, but the latter is a few weeks off... Could anyone give me a direct link to the materials before I try to rebuild a head with cotton balls rabbit tails and coat hangers?
