I'm on Smoking Pipes looking to buy some stuff and I'm a bit confused. I know what Fresh means, but some pipes have say condition discolored bowl, so I'm sure they're preowned. Some say unsmoked, and others say nothing at all. All the pictures look like brand new pipes. How do you know whats used and whats new? And theres like 6 of the same pipe for the same price. Then a more expensive same.model pipe that says the thing the others did?
