Today the humidity got up to 75... I'll try switching out the glass and using an ordinary oasis and seeing if it holds.
The size thing is an issue. I can't see stocking this with that many cigars, maybe 25 tops. I just don't smoke that much. Maybe I'll get some old cigar boxes, rip off the lids, and hold the cigars in there. That might help the humidity. The outside of the humidor is beautiful, it's nice furniture but, in some ways its impractical for a modern cigar smoker.
The old cigar box I am using as a sweet/flavored humidor is not working well, humidity keeps falling. I think because the underside is bare unsealed wood.
If you sand off the finish on a humidor I would recommend at least putting a silicone furniture polish (Pledge, Bold, etc.) or carnuba wax on the outside, if not something like tung oil (the real stuff), to create a moisture barrier. Orange oil will evaporate very quickly.
