Product Description

Oasis Ukulele Humidifier. With 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-Percent 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.

5 Stars
Nice little humidifier at a great price!
I use an Oasis humidifier in all 3 of my ukuleles. They seem to do the trick, in the dry climate that I live in. Reviews say that you might need to replace it after a year, so I'll just plan for that. It's important to keep your wooden stringed instruments from drying & cracking!
