Oasis Ukulele Humidifier OH-18

The newest humidifier by Oasis has two unique features. The mounting system allows the humidifier to hang horizontally inside the ukulele rather than vertical (like the guitar humidifier). Secondly, the humidity output is about 50% of the Royal Blue Oasis guitar humidifier, to accommodate the smaller instrument size. This also allows the humidifier to last twice as long between refills.
