Milan Tobacconist. Roanoke, VA. I sometimes take my lunch break and have a smoke there. I'm smoking their Butter Berry right now and I love it. Great folks there too, employees and patrons.
I have four meers directly from Bahri Tuner in Turkey. Got them at a great price because there's no middle man. Two are custom jobs. You can look him up at www.meerschaumpipemaster.net . His stem work is great and he matches each stem to each pipe. They smoke great too!
That's completely stupid. According to scientists everything causes cancer. I'm sure if you look hard enough there is a scientist out there that has "proved" that breathing air causes cancer, because everyone who gets cancer breaths air. These people need to find better things to waste money on.
I usually use them two or three. It depends on how much junk is on them. I'm a heavy aromatic smoker. If you're more of an English or non-aromatic then you could get more. I just let them dry, it usually doesn't take long.
I've got one. It smokes fine. The keystones work well and you can use them more than once. Just let em dry. I haven't tried in any other pipes but I've heard they work well if you put them in the bowl.
