Humidor Planet Waves PW-HPK-01

Planet Waves Humidifier Pack PW-HPK-01 for Guitars

The two-way humidification system is the only maintenance-free, two-way humidity control system for guitars.

It automatically maintains the optimal 45-50% relative humidity level inside the instrument case, eliminating the guesswork and potential problems associated with filling a humidifier. Unlike rechargeable humidifiers, this system provides true "bi-directional" humidity control by adding and removing humidity on demand. No more manual adjustments based on seasonal changes, geographic locations, temperature or other factors.

The two-way humidification system comes with 3 humidipaks and a soft mesh bag that will not damage the finish of your instrument. These packs last between 2 and 6 months and should always be kept in a sealed environment such as a hard case. Once the packages become firm, discard them and replace them.
