Here at Boveda we know you love your instrument. It's a part of your musical identity. Musicians all over the world use Boveda to keep their instrument in optimal shape by controlling the humidity level in the case. Without proper humidity control, wood instruments will not perform at their maximum ability and even worse can be damaged. To maintain their shape, wooden instruments need to be stored at a stable 45-55% RH (relative humidity). Wide fluctuations in humidity will cause the wood to expand or shrink, which puts stress on the instrument and degrades its performance abilities. Take the work out of managing humidity for a wooden instrument. Avoid humidty damage with the global leader in 2-way humidity control. Automatically adds AND absorbs moisture as needed using all-natural salts and pure water sealed in a leakproof vapor phase osmosis membrane.
