Is a dry box really that bad? I have used a dry box before, and found it satisfactory. When paired with a small bucket of "Thirsty Hippo", the hydrometer reads 30%. That's a little overdoing it, apparently, but it seems to protect my gear alright. My dad has been using the Tupperware solution before I was born. No issues there either. I truly believe it a simple matter of managing the humidity.
