and about the knock offs...i don´t put my name and tattoing time on a crap tool. Good tools are expensive, you can do a skull with anything you want, coal, ballpen, piss and mud, but if you want to do some better skull you need to spend the cash...watercolor, oil, marker, canvas, wathever.My point is i can do a skull drawing on the floor but why i should do that if i can do better? my two cents
