Boveda 8 gram packs are the appropriate size for smaller enclosed travel humidors. The 8 gram size is not big enough for full size wood humidors, we would recommend using the 60 gram packs instead.

Boveda is scientifically engineered to maintain a precise relative humidity in an enclosed space. Each Boveda consists of a specially prepared saturated solution of pure water and natural salt. This saturated solution is contained within a water-vapor permeable “reverse osmosis” membrane. Within an enclosed container, Boveda maintains a predetermined level of (RH) by releasing or absorbing purified water-vapor as needed through the membrane.

These are perfect for travel humidors, small bags and also for roll your own or pipe tobacco.
