I have built my own desk top humidor. That was before I moved to a winador. My opinion, for what it's worth, is that you should use the box as a show piece and not as a humidor for long-term storage. A good humidor should be air tight. That is why so many people eventually move to Tupperware, coolers or wine fridges. It is very very difficult to maintain a consistent humidity in wooden boxes unless they have a sophisticated seal at the lid. If you can do that then go for it ..... and lets see a picture !
