Information

DETAILS:

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.

20-Pack Brick: Packaged in a heavy-duty plastic bag that is resealable using its attached tape enclosure. Each Boveda is not individually overwrapped.

    Poor product. Does not work as described.

    I purchased the started kit and followed instructions yet my hygrometer shows nothing over 42%. I reordered another set. Still after 1 week inside the case “seasoning” WITHOUT the guitar still 42%. Replaced the hygrometer. Same result. So if you want 42% instead of 49% this poorly made and falsely advertised product is for you. Otherwise A COMPLETE WASTE OF YOUR HARD EARNED MONEY. Stay away.

    Works Wonderfully

    I actually use this for my lettuce to pull out extra moisture so that it lasts longer for making salads.

    Works just as intended.
