Title: A bit big for ukulele cases, but works.
Review: I know this is probably more for a guitar, but I have a few solid wood ukes that need humidity to be happy, so I bought this. You open the lid, submerge it into water for 5 minutes (you may see some bubbles escaping - that's cool), and then wipe off the excess water, close the lid and pop into your case. Do this once-twice a month and you're golden. Works well by me.
