Oasis OH-18 Uke Humidifier

Oasis OH-18 is made especially for ukulele to the same exacting standards used for their guitar humidifiers. The unit hangs at an angle from the strings into the soundhole and does not touch the body of the instrument. Output is about half of the best-selling OGH1. Still shrivels to indicate it is empty and needs more water. IMPORTANT: READ THE INSTRUCTIONS.
