D'Addario Two-Way Humidification System

D'Addario bring Boveda's patented, automatic, two-way humidity control technology as part of their instrument care line. Boveda's technology maintains a constant 45%-50% relative humidity level inside your instrument case. Based on scientific principals, the patented humidification system completely eliminates the guesswork and anxiety around maintaining your instruments proper humidity level.

No more dripping sponges or manual adjustments due to seasonal changes, geographic locations, temperature, or other factors. Unlike all refillable humidifiers, this humidification system provides true "two-way" humidity control by releasing or absorbing purified water vapor to maintain a constant 45%-50% RH within a sealed environment.

Simply place the humidification packets with the included pouches into your instrument case as instructed, close the lid, and that's it!
