Oasis Ukulele Humidfier OH-18
The Oasis Ukulele humidifier has two unique features:
-The mounting system allows the humidifier to hang horizontally inside the ukulele rather than vertically (like the guitar humidifier).
-Secondly, the humidity output is about 50% of most guitar humidifiers to accommodate the smaller instrument size. This also allows the humidifier to last twice as long between refills.
