Turning this special box in a Humidor?

[SuperChuck]

Have you tried just testing how it holds humidity?

It looks like the lid has a nice little lip to it. It may do the job on its own.

i dont think you would have to do anything to that box to make it a humi. check to see if it holds RH well and i think it will. if not then you have to find out where your leaks are and seal them with some cedar strips. Either way it shouldnt be a hard project at all.
