Boveda 2-Way Humidity Control Pack 62% 67g (20 Pack)

Boveda 62% RH Size 67 2-way humidity control packs, 20 per pack. Each Size 67 pack keeps up to one pound (454 g) of material at a steady 62% relative humidity.

Boveda 2-way humidity control automatically adds or removes moisture to hold the exact RH printed on the pack. 62% RH suits people in dry climates or at high altitude, and anyone who prefers material that stays soft and sticky. Place the pack in an airtight jar, bag or container and close it; no activation is needed.

Replace the pack before it becomes completely rigid. Do not mix different RH levels in the same container.
