Your wooden stringed instruments deserve to be protected. They are investments that require steps to ensure their value grows over time. The Kyser® Lifeguard™ Humidifier does just that. If you store your instrument in a dry area, simply immerse the Kyser® Lifeguard™ Humidifier in water, shake off excess, and then position it in the sound hole. It will preserve the wood on your instrument by keeping conditions at the proper humidity.
