Ive been reading a lot about snuff since I put my order in, and im looking to make a second, and more educated purchase, very soon. So can some of you veterans help me out here? I got got a few questions. Firstly, what separates a Schmalzler from other snuffs? Is it just the name or is it a type of snuff, like SP and Toast? Also what does the color of the snuff mean? One website i was on organised their shop by black, brown, and gold snuff, and i also noticed SG or GH had snuffs with those different colors. Also I have been told that tap boxes do not keep snuff fresh unless it is poschl, because of the oil in it. I figured thatt buying a 25g tub of GH would go bad because i wouldnt be able to use it all, but now im being told the tap boxes i orderd will go bad, is the tub like airtight or somthing?
