Sorry 'baby finger' I must differentiate or at the very least define. The price you pay for butane is in direct proportion to the amount of crap left behind after evap. ergo 1.55 for 6-8oz can gets lot's of crap, test; spay on glass all that white to beige stuff is not good for injestion even as smoke. with a triple filtered butane at $10 + no residue less toxic.
