Made by Kristin Bertrand in her NYC Workshop, these humidifiers are a must for any woodwind case during the dry winter months. It is made of water absorbing gel that will not leak or mold and requires much less maintenance than the traditional water and sponge humidifiers.One humidifier is sufficient for single cases. Double cases, bassoons, and bass clarinets might opt to use two.
