An easy-to-use, no mess, low maintenance guitar humidifier. The Humitar rests on the strings of your instrument and hangs into the soundhole. The innovative Humid-i-Bar sponge has anti-drip properties, holds 10x its weight in water, and safely releases moisture evenly. This means less monitoring on your end. Time to check the Humitar? Easy. Pop the top and touch the insert. If it's wet, leave it. If it's dry, it's time to rehydrate. To rehydrate, simply remove the Humid-i-Bar sponge, soak it in distilled water, and you're back in action.
