The Boveda Humidity Pack Double Packet Holder is designed to securely hold two Size 70 Boveda humidity control packets, providing a safe and effective way to regulate humidity in your instrument case. Its soft, leak-resistant fabric lining allows Boveda’s pure water vapor to circulate freely, maintaining a consistent relative humidity (RH) between 45% and 55%—the optimal range for wooden instruments like acoustic guitars, cellos, and other large-bodied instruments.

Simple to use and protective by design, this holder not only extends the life of your Boveda packets but also prevents direct contact with your instrument. Just insert two Size 70 packets, place the holder in your case—under the neck, headstock, or in an open area—and enjoy maintenance-free humidity control. Whether you’re safeguarding your guitar or cello, the Boveda Double Packet Holder ensures stable conditions and long-term protection.
