Ukulele wood needs moisture to play and look its best. Dry wood can warp, shrink and worse yet, crack! Music Nomad the leader in equipment care products, has developed an easy to use, no mess, and a low maintenance Ukulele humidifier. The Humilele rests securely on top of the strings to safely and evenly hydrate your Ukulele to avoid these problems. Fits in all Soprano, Concert, Tenor Baritone Uke Soundholes. The overall width is 2" wide and it hangs below the strings 2" giving it plenty of room to fit in all soundholes. Our innovative Humid-i-Bar sponge holds a lot of water and has anti-drip properties. This means less monitoring on your end while rest assured you're fine Ukulele is being cared for. Time to check the Humilele? Easy! Pop the top, touch the Humid-i-Bar; if it's wet leave it, if dry, time to rehydrate. Rehydrating is a cinch - remove the Humid-i-Bar sponge, soak it in distilled water and you're back in action. Easy, no mess and low maintenance. That's Music Nomad quality, raising the bar in the equipment care industry.
