I think it would be ok, but I really dont know. I have some that is a few years old that I\'ve left on a shelf in a shoebox that is still in perfect condition. It\'s 3 or 4 years in storage. I know it\'s in good condition because I pulled it out and played with it last month when I got an urge.
Anyway, my point, I dont think you need to go to that extreme to store it. When they say \"cool dry place\" they mean typical room temperature, not in the window/sunlight or not on top of the radiator or fridge etc.
