Humidipak Two-Way Guitar Humidity Control Packs

Humidipaks are two-way humidity control packs which automatically release or absorb moisture as needed to maintain the ideal humidity level for your guitar. Use Humidipak Restore if your instrument is dry and needs to be returned to the proper humidity level. If your instrument is already at the proper relative humidity, Humidipak Maintain will sustain this level inside your case.
