just remember with the silica packets, they can only absorb so much moisture , you need to buy them new in a sealed container, if you pick them out of pill bottles and other places then they will be used up, they do not keep absorbing forever, they only hold so much!
the big thing you want to avoid is temperature highs and lows, and temperature swings, and you what to keep it at the same humidity, like 50 percent. keep it out on sunlight, store them on an inside wall, keep them out of the basement and store them in a rat prof bug proof container
