It sounds like a humidor. Can you post a picture? Any ways, if it is fairly air tight it can be used as a humidor. You just need to add a humidifier. It can be as simple as a florist sponge in a bag with some distilled water on it, or you can order some humidity beads from www.heartfeltindustries.com . As for leaving your cigars in the cello or tubes, that's personal preference. I usually keep mine on. Some people take them out. If they are already properly humidified then I would just leave them as such and throw them in your humidifier with some distilled water.
