The aficionado golden rule: when you are about to chose a humidor, take one capable of storing a larger quantity of the cigars you want to keep right now.
Where you buy a humidor, do not buy it thinking the exact number of cigar you want to store. In a very short amount of time you are gonna finish the room and you will regret it. It always happen like this! So, buy a bigger one (without exaggerating), spend a little more and forget any future disappointments!
