I've been barely getting by with 2 Xikar travel humidors, that for their size don't really hold a lot, once you factor room for the foam and humidity packets.

So I went wild and picked up this Yeti GoBox 15 on sale, then stuck a humidifier unit to the inside of the lid.

I'm currently waiting on 2 stackable cedar trays for the bottom, so that the lower cigars stay more organized and contained while in movement.
