Humidity Control Process Under Full Control

Extend the life of your valuable guitars and especially sensitive acoustic instruments with Boveda's two-way humidity control kit. Fluctuating humidity levels are not good for any wood, especially acoustic. It can lead to warping, drying out, or even cracking of the instrument. Not only does this ruin the appearance of your instrument; over time, it can destroy its tone or ultimately make it unplayable. Boveda offers full control and maintains humidity at the precise percentage level best suited for wooden instruments. It cannot be compared to any humidifier you have known before.

Boveda's unique product uses a specially formulated solution of pure water and natural salts encapsulated in a vapor-permeable membrane to maintain a constant relative humidity level between 40% - 50% when placed next to your instrument, thus preventing destructive humidity fluctuations. You can be assured that your instrument is kept in an ideal environment. This set contains four 70-gram packs maintaining a relative humidity of 49%, ideal for acoustic guitars, cellos, double basses, bassoons, clarinets, and more.
