To keep your wood looking good, just give it some water. Kyser Lifeguard Classical Guitar Humidifiers are set-it-and-forget-it life preservers for safe storage and sweet sound. The disc-shaped bodies hang perfectly from your guitars soundhole so the sponge inside can slowly distribute water into the air, naturally regulating humidity to ensure the integrity of your instrument for years to come.

Designed for standard classical guitars with 3 3/8 to 3 3/4 soundholes.
