Two giants in the humidity business, together. The Xixar by Boveda humidity packets use a special blend of super saturated salt solution (try saying that 5 times quickly) to maintain a constant level of humidity that never fluctuates or cycles -preserving your cigar's natural oils and sugars, allowing them to improve with age.

Benefits:

• Easy to use, simply unwrap and place the correct number of packets in your humidor and you're ready to go -never guess if or when to refill your humidifier again
• Monitors ambient humidity by adding or removing moisture to maintain the RH engineered into the pack to an accuracy of /- 1%*
• Will not humidify beyond the RH on the packet, it's impossible to use "too much"
• Reverse Osmosis inhibits the passage of impurities, ensuring that only clean, pure water-vapor passes through the membrane into your humidor
• Maintenance free, no need to monitor or refill your humidifier. Replace packet when firm.

*Every XIKAR 2-Way Humidity Control RH is accurate to /- 1% in an air tight environment, which humidors are not. It's common that the actual RH of your humidor will stabilize up to 5 points lower than the XIKAR 2-Way Humidity Control RH you're using, due to humidor quality and ambient dryness.
