This special moisture regulator prevents moisture and excessive drying of guitars, etc., from rusting, cracking, sledding, and other instruments and preserves the tone and longevity of your musical instrument. When the humidity around the instrument becomes high, it absorbs moisture and releases moisture a little by a time as it dries. It is highly effective when storing string instruments such as guitars, violins, mandolins, etc. and other instruments that are too dry or too dry.
Effective period: 3 months; For rainy seasons, we recommend replacing it every 1 to 2 months
