I have three pipes. not in any sort of rotation. I just picked up my first cob the other day after reading a thread on them here. I typically go to a smoke shop but they were closed for the holiday. I bought the only cob a local drug store had. It is a missouri meerschaum, in my opinion it is pretty low quality, which was to be expected. I would like to know if there is a difference between quality/ brands/ finish or non finish...ect. It does however provide a nice smoke. MY main question is this cob has an amber color stem that is see through. I do not like this. So without thinking, i colored it black with a permanent marker. Will this affect anything? will my saliva possibly cause it to wear off in my mouth? I do not wish to spend another seven dollars for another one. I am a newcomer so Any Suggestions of any sort are greatly appreciated. Thanks. - Mr. Pink
