travel humidor project?

How you finish the inside or make it air-tight depends on how you are going to use it. If just for weekend herfs, I wouldn't worry about it being air-tight, just put your perfectly stored cigars in ziplocks and they will stay good for days. If you plan on using it for longer than a week, I would try to get it air-tight and use beads or humi packs.
