Martin Guitar Humidifiers are made from the finest materials available. The tubes are extruded from high-quality, non-vinyl, non-allergenic resin—soft enough not to exert pressure around the soundhole, yet sturdy enough to minimize contact with the internal parts of the guitar. Inside, a water-absorbing stem holds up to ten times its weight in water and slowly releases moisture through the outer holes.
