Protecting your guitar just got easier. The ultimate Humidity Care System combines our two best sellers with our easy-to-use, no-mess, and low-maintenance guitar humidifier The Humitar, and The HumiReader a humidity and temperature monitor that is simple, accurate and reliable. The Humitar safely releases moisture evenly to eliminate potential problems such as warping, shrinking and, worse yet, cracking. The Innovative Humid-i-Bar sponge holds a lot more water than similar products. This means less monitoring on your end while resting assured your fine guitar is cared for.
