Boveda Two-Way Humidity Control MB49-08-10P Pack of 10 (8g each) for Maintaining 49% Humidity

This two-way humidity pack absorbs or releases moisture to maintain the desired level. Extend the life of your valuable acoustic instrument with Boveda's two-way humidity control pack. Fluctuating humidity levels can damage your acoustic instrument, causing warping, shrinking, and cracking.

Not only does it ruin the aesthetics of your instrument; over time, it can destroy its tone or eventually make it unplayable. Boveda's unique product uses a specially formulated solution of pure water and natural salts encapsulated in a water-vapor-permeable membrane to maintain a constant relative humidity level of 40-50% when placed next to your instrument in its case, preventing damaging humidity fluctuations. You can be confident that your instrument is kept in the ideal environment. When your packs are saturated and firm, simply replace them with Boveda replacement packs. This replacement pack includes a total of 10 packs with a relative humidity of 49%, each with a shelf life of 2 years; so you can have them on hand whenever you need!
