OK, noob question here. I bought one of those leather, cedar lined, 10 count travel humidor that's shaped like a book and where the top slides off. Is it necessary to season these? It looks to have a small veneer of cedar inside, and I assume it would warp if I put water to it. Also, how long should my smokes be OK in this thing without humidification? Would a 7 day business trip dry them out?? Thanks in advance for the help!
