Boveda B49-70-OWB 49% RH Humidifier Replacement Packs-Size 70

Love the ease of using the Boveda Starter Kit to balance humidity in an instrument case? When it's time to replace expiring Boveda, this is the pack for fretted and bowed instruments and woodwinds.

Using Boveda in an instrument case:

Requires zero maintenance—no more filling messy hoses and snakes and wetting sponges
Maintains an ideal relative humidity range for instruments—45-55% RH
Prevents wide fluctuations in humidity that cause the wood to expand or shrink, and degrade its performance abilities

Keeps wood instrument in the safe zone—Automatically achieves and maintains a constant relative humidity (RH) level between 45% and 55%.

Prevents humidity fluctuations. Exposing your wood instrument to humidity swings day after day—going in and out of air-conditioned venues or traveling by air—can throw off its measured alignment and cause permanent damage.
