Take the guesswork out of seasoning your new humidor. Boveda 84% RH 60g seasoning packets guarantee a complete and even equilibration of moisture without causing mold, a mustiness smell, or warping—as commonly happens when following traditional seasoning methods. Use 1 packet for every 25 cigars that your humidor can hold. Shelf life: 2 years inside the plastic wrapping. It takes 14 days of exposure to 84% relative humidity to slowly and completely moisturize a wooden humidor. With the Boveda Seasoning Kit, you are sure to get the best results whether you are seasoning a new humidor or re-seasoning your humidor in the winter. After 14 days, replace the seasoning Boveda (84% RH) with regular Boveda 65% to 75%.This product comes in three presentations. You can buy the single packs individually wrapped in plastic. The 12-pack refill has 12 individually wrapped large 60 gram packs of Boveda 84%. The Bulk 20-Pack brick saves you the most money as each Boveda is not individually wrapped in plastic, instead the 20 large 60 gram packs are packaged in a resealable plastic brick. The bulk pack also saves you time as there is no need to unwrap each unit.
