Boveda 320 Gram Humidity Pack | 75%

Help compensate for moisture loss in an extremely dry climate or a very drafty wood humidor with the Boveda Size 320 75% RH two-way humidity control pack. One Size 320 provides the humidity-control capacity of five Size 60 packs and is recommended for containers designed to hold up to 100 cigars. Do not use 75% RH for long-term cigar aging or in airtight storage such as tupperdors or humidor bags. Do not mix RH levels or use with other humidification products. Boveda recommends replacing humidity packs about every three months.
