I have read a great deal in discussions herein about how to keep one's open tins from drying out. I've also of course have read a lot of recommendations on how to handle the problem but I can't recall anyone talking about what I've come up with although many probably have. I bought a couple of cheap Rubbermaid containers with snap on lids that are about 9x14x3 inches. Into these I put about fifteen tins of what I have open. The container lids do not seal well and would ordinarily not much delay tins from drying out so I put into each container a couple of inexpensive hockey puck humidifiers I got from P&C.
Despite the lids not sealing all that well it's been six months now and there are still some tins in there which I have not finished in that time but they have not dried out, at all, and in fact some have rehydrated from their previously too dry state. All I've done is refilled the pucks with water every week or so. The arrangement has proven entirely satisfactory. Even small samples in baggies, which tend to dry out quickly, have benefited from the setup. Total cost is under ten bucks and I flat do not have to worry any more about open tins drying out. I have also not noticed any cross fertilization of taste or aroma among the different blends, probably because the non-sealing lids allow for a little air exchange. I suspect that this setup would not work as well with aros but I don't smoke them so I haven't been able to try that out. If one does smoke aros then a separate container for them would be a must.
