I believe most of the FOG's on CP will say that you need 100% cedar. That's what a number of them told me. (Here's my topic on the exact same issue.... http://www.cigarpass.com/forums/index.php?...c=43253&hl= )In order to provide savings for our customers and get the same value, portions of our humidor interior are made of cedar wood. Once the humidor is closed everything inside is sealed. The cedar smell will remain in the box giving positive effect on the flavor of your cigars. Therefore there is no need to make the inside of the humidor completely of cedar. If you research cigar humidors, there is no 100% cedar humidor.
