Using High-Absorbency Boveda in an instrument case:

• Protects wooden instruments that are exposed to year-round extreme humidity of 50+% (Lower humidity? Choose B49 packs for wood instruments.)
• Automatically maintains constant RH between 40% and 60% for instruments in high humidity climates
• Prevents warping and mildew build-up
• Curbs humidity fluctuations that throw off an instrument's measured alignment and cause permanent damage (think going in and out of air-conditioned venues, traveling by air, performing outdoors, etc.)

HOW TO USE

BEFORE USING BOVEDA:

• ALWAYS insert Boveda into a leakproof holder before using in your instrument case. The holder acts as a liquid barrier if a packet is accidentally punctured while extending the life of your Boveda packets. The patented interior material allows water vapor to pass through to your instrument. The exterior is soft, like a polishing cloth, so it doesn’t scratch the finish.
• DO NOT mix B49HA and B49 or different Boveda RH levels  within the same instrument case. 
• DO NOT use other humidification products with Boveda in the same case because they will fight against each other and reduce the efficiency of Boveda.

STEP-BY-STEP INSTRUCTIONS:

1. Slip the Boveda pack into the pouch of its leakproof holder. (DO NOT OPEN the Boveda itself.)
2. Place in the case anywhere that allows for airflow and prevents puncture when you close the case:
   - Under the neck or headstock
   - On the strings
   - Open area in the case
3. Close the case's lid. Always keep your case closed when using Boveda.
