I've read a bunch of stuff about making a tupperdor on various sites, but I still have one question. I know its okay to put whole boxes in there. But what about air flow inside the boxes. I'm thinking maybe the boxes should be cracked open or about just removing the box lids entirely.
What do you think?

Good to decent boxes are porous. Don't worry. Cracking the boxes certainly couldn't hurt. That could disperse a little ammonia smell but I've never had a problem.

I have never had a problem with holding boxes in the tupperdor.But I never had them in there more than a year.Ialso remove the cello from outside the box of cigars.

yeah I got several of them tuppers and no probs with the boxes. for sure remove that ugly cello wrapper. I open the box only cause I want to look at them babies from time to time
