Boveda 65% RH Size 320 MB65-320-OWC: Large-Scale Humidity Control, Dialled to Your Preference
When a collection spans hundreds of cigars across a large humidor or dedicated cigar cabinet, you need a humidity pack with the capacity to cover the full space — and the precision to hold exactly the level you want. Boveda Size 320 at 65% RH delivers both.

The Size 320 is the largest pack in the Boveda range, containing up to 320g of saturated salt solution — enough to maintain stable humidity in large-capacity humidors, cigar cabinets, or full retail cartons continuously over many months. The 65% RH level — slightly higher than the standard 62% — suits connoisseurs who prefer their cigars with a fuller, more supple draw, or those compensating for environments with greater air circulation. Boveda's two-way technology self-regulates continuously with zero manual intervention and no risk of liquid contact with cigars. The Retail Cartons format makes bulk purchasing and long-term stock management straightforward.

Boveda 65% Size 320 — professional-grade humidity management for the serious collector, fully automatic from the moment you place it inside.
