D'Addario Humidipak Restore Kit PW-HPK-03

This unit is for conditioning (or re-humidifying) a dried out instrument.

D'Addario Humidipak is the only maintenance-free, two-way humidity control system for guitar. It automatically maintains the optimal 45%-50% relative humidity level within your instrument case, eliminating the guesswork and potential mess related to refilling a humidifier. No more manual adjustments based on seasonal changes, geographic locations, temperature, or other factors.

Note: Humidipak is designed for restoring and maintaining instrument humidity. This product is not intended for dehumidification in high humidity environments.
