Why purchase packs from vendors or hydro stores that have had them sitting around for months? MyPharmJar specializes in herb preservation and due to our tight inventory management system, we replenish our Boveda packs at least every two weeks, sometimes more often. You can be assured you’re getting the freshest, latest humidity packs when you purchase from MyPharmJar. We ship orders the same day until 4 pm PST and 9 am PST Saturday cutoff!

Humidity packs will solidify as they expire. When there aren’t many soft spots left, then you’ll want to replace them. Pronounced crystallization and hardening of the corners first is completely normal and a part of the usage process. You can expect 2–6 months of usage life depending on the container and external environment.
Our Humidity Packs have a 2-year shelf life in the original packaging. If you no longer have the original package, it is best to use an airtight container with a strong moisture seal. For example, a humidor bag or MyPharmJar, glass, and metal containers with rubber seals.
