Information

DETAILS:

Using High-Absorbency Boveda in an instrument case:
  • Protects wooden instruments that are exposed to year-round extreme humidity of 60+% (Lower humidity? Choose B49 Standard Refills 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 Boveda 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 Boveda 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.

PACKAGING:

4-Pack: Packaged in a resealable high-barrier heavy-duty plastic bag with a zip closure. Each Boveda is not individually overwrapped.

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

Unopened, Boveda can last up to 2 years.

    They work for me.

    I have been using the High Absorbency Packs since I first learned of them a few years ago. They work exactly as advertised, keeping my guitar display case and guitars still in their cases at around 50-52% (close enough to 49% given the error range of my hygrometers), even on days when the room humidity exceeds 70%. I haven't found any other product, short of an electric dehumidifier, that gives this result.

    Love the Product!

    I love the product and its simplicity. I wasn’t planning on the automatic quarterly agreement when I first ordered the product but didn’t see any option to buy occasionally. Otherwise all is good.

    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.
