Dampit Humidifier NEEDS WEIGHT
Dampit consists in a green soft rubber sleeve encasing an open cell sponge. Once filled with water and placed it inside the instrument through the F holes, the Dampit will slowly release humidity and help preserving the instruments when the surrounding environment is too dry. It is specifically indicated during winter.
Note: it is better to remove any excess of water and to wipe the tube with a cloth before placing it in the instrument.
