The XIKAR Boveda 75% 2-Way Humidity Control 60g packs, supplied in a bulk pack of 100, provide precise humidity regulation for larger cigar humidors and travel cases, maintaining 75% relative humidity (±1%) through patented two-way technology that both releases and absorbs pure water vapour to counteract environmental fluctuations. Each 60-gram sachet utilises FDA-compliant natural salts within a semi-permeable reverse osmosis membrane, delivering clean moisture without impurities or risk of over-humidification, supporting substantial collections of 100-300 cigars depending on humidor volume and ambient conditions. Ideal for wooden humidors in drier climates or higher-capacity storage where traditional devices struggle with consistency, these maintenance-free packs remain effective for 2-4 months before requiring replacement when they become rigid. Completely spill-proof and odourless, they eliminate the need for constant monitoring or refills whilst preventing common issues like tobacco beetles or wrapper splitting, with seven RH options available for personalised calibration. This professional-grade solution transforms collection management into effortless precision, ensuring cigars age gracefully whilst preserving essential oils, sugars, and complex aromas for optimal smoking character.
