Boveda Humidifier MBVMDK Two-Way Humidity Control - 1x 49%RH Size 70 + Case - 1pc

The two-way humidifier 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 set. Fluctuating humidity levels can wreak havoc on your acoustic instrument, causing warping, shrinking, and cracking.

Not only does this destroy the aesthetics of your instrument; over time, it can ruin its tone or ultimately render it unplayable. Boveda's unique product uses a specially formulated solution of pure water and natural salt encapsulated in a 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 swings. 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 one pack with a relative humidity of 49%, each with a shelf life of 2 years, and a Boveda case, so you have them on hand whenever you need!
