The Paganini Humidifier is designed to slowly release moisture, then create and maintain the proper humidity to help prevent cracking and warping of your instrument. To use your Humidifier, immerse it in water for 15-20 seconds. Squeeze lightly to remove excess water and wipe the outside of the tube and the ends. Insert the Humidifier in the F hole (sound hole) of the instrument until all of the moisture-release holes are inside. Check your humidifier daily to make sure the moisture level remains constant. Wait unit the Humidifier is nearly dry before re-dampening.
