Woulda paid for me to check out this thread before starting a new one about Masons.

Most of my open tins and baggied tobaccos are stored short-term (anywhere from 1 month to 12, depending) in freezer bags. Been doing that for a few years now and I've never had a problem with anything drying out.

My suggestion though is to buy that case of Masons at Walmart for, what, $9? Then fill 'em up with some tobacco!
