I've looked at the same humidor for a while and was thinking of picking it up. If I do I'm going with wood but that is because I have a 3 yr old boy, and more on the way, and

  1. Don't need the finger prints
  2. If they don't notice them the better for me and my cigars
  3. My wife wants to get a dog, see #2
  4. I have a bunch of friends who like to mooch my sticks - again see #2


But if I didn't have those concerns I would probably go with glass because I could sit there and stare at those lovely little bundles of agricultural joy.

So I'm voting wood.
