Boveda's 2-way humidity control technology automatically protects your wooden instrument against warping, cracks and other damage caused by lack of humidification or too much humidification. Boveda maintains a constant 40%-50% relative humidity level within your instrument's (closed) case. Improper storage is the greatest constant danger to the condition of a wooden instrument. If not properly stored in a stable environment, your instrument will lose the specific geometry built into it while it was being crafted at the climate-controlled factory.
