I don't have a traditional humidor but use these in my wineadors and cooler and they would work in a humidor. I also chew and the "tins" are plastic. I cut out the inner circle on the top, fill with beads and stretch a piece of mesh across the top before snapping on the lid. They are like a "puck" that you can set on the bottom, on the side against any wall or even stick a magnet on it and hang upside down under the lid or tray. Happy to post a pic and save a few empties for you if you're interested.
