Conduct a thorough seasoning in just one-step with Boveda 84% RH. There's nothing to measure, fill or spill. Just add the pack to an empty humidor and Boveda will automatically prep your humidor for cigar storage. 84% RH is for: Seasoning wood humidors before adding cigars Completely humidifying the cellular structure of the wood inside humidors Preventing new humidors from robbing moisture from cigars and Boveda 72% RH maintenance packs Re-seasoning wood humidors A Single Size 60 is for: Up to a 25-count humidor.
