I got a YETI Roadie 20 cooler 6-8 months ago that I've been using for box storage. They seal very well and have great insulation. Have yet to use any Bovedas in it yet and it holds high sixties. The cigars are the humidification as they come in a bit wet. I just transfer some over to my desktops as needed. I went on a little buying spree back when and couldn't fit anymore boxes in it so I bought one of those heavy duty five gallon buckets with the screw top lid on it for the overflowing boxes. Tossed some cedar and one Boveda 65 in it and it holds amazingly well with 4-5 boxes in it. I store it in a cool closet and it's worked for me...Whatever gets you through the night...
