The huge success of our original blue Oasis® “sound-hole” Guitar Humidifier brought numerous inquiries about how to provide humidification for other wooden instruments such as violins, violas, cellos, jazz guitars, and some woodwind instruments like clarinets and oboes. After careful consideration and research, we developed the OH-6 Case Humidifier. This style of Oasis® humidifier attaches to the inside of your instrument case. To accomplish this, two powerful neodymium magnets are inserted in the seam of the humidifier. The magnets attach to either a steel clip or a stainless steel strip with adhesive backing (both are provided with the humidifier). The steel clip fits over the side of your case, providing a flat vertical surface to which the magnets can adhere. The neodymium magnets are strong enough to keep the humidifier attached to the clip or strip, but still allow the user to remove the humidifier with ease.
