I am a little over cautious and have probably over done it a little. I like to keep my seeds in a 1/3 of a dram air tight glass container. I then place this in a small bag and place both of them in a small plastic container packed with loose desiccant. That is next placed in a heavy plastic lock-top style container with large desiccant bags and humidity indicator cards, then finally placed for long term storage in the bottom of a deep freeze. Probably overboard but I at least know they are good and safe for the long haul.
