How do I store Boveda I'm not using?
Keep Boveda in its original packaging until you're ready to use it. Close and reseal any open multi-pack bags. Or store Boveda in an airtight container.
Boveda has a 2-year shelf life in the original packaging, like its clear overwrap or resealable bag.
If you no longer have the original package, store Boveda in an airtight container with a strong moisture seal, like a Boveda Humidor Bag, Tupperware, or glass jar or metal container with a rubber seal.
DO NOT mix Boveda relative humidity (RH) levels within the container.
