Boveda Boveda has knocked it out of the park with this one! Their patented 2-way humidification system ensures that the humidity in your humidor is regulated to the perfect level. If the level drops the Boveda packs releases moisture bringing it back up. If the humidity rises, the Boveda pack soaks it up, keeping it at the perfect humidity no matter the atmospheric changes. Unlike distilled water and PG solutions with sponges/gel/crystals/beads which can affect your tobacco products, Boveda's reverse-osmosis membrane only releases pure water vapor and Boveda will never damage anything through direct contact.
Boveda Wooden Packet Holder For use with 4x 60g Boveda Humidity packs, The wooden holder mounts to the lid of any humidor with a magnetic, or velcro fastening (both included).
