Humistat #3 Musical Instrument Case Humidfier
Keeps wood instruments from drying out
Unlike many guitar or case humidifiers that use a sponge or other absorbent material to hold water, this clear plastic disk is filled with water but uses a special material that swells up to regulate the rate at which moisture leaves the device. You can see at a glance when it needs refilling, it refills in seconds, and to a degree you can regulate the amount of moisture in the case. Very cool. They recommend the use of distilled water which you can buy at the grocery store and keep in a corner — I guess a gallon will last nearly forever.
