On another note. I assume you have other solid wood ukes. You seem to have a collection yourself. But, just in case not, here is a tip. I make my own humidifiers for pennies. I take the little plastic cans 35mm film comes in. If you have a 35mm camera, or know someone that does, you/them probably have them laying around in your camera case, or even thrown out a bunch. If not, any film processing place would probably give you as many as you wanted (they throw them out in droves). Take an ice pick, or other sharp object, and puncture 5 or 6 holes in the lid of it (kinda like a salt shaker). Pack the plastic can with cotton balls tightly (5 or 6 cotton balls) fill the can with water enough to soak the cotton, but not so much as it pours out. Soak em, turn it upside down to pour out any excess water. Put the cap (with the holes you punched) back on, and toss it in your Uke case.. Refill with water as needed to keep the cotton moist. The same type simple humidor like this sells for $10 and up retail. You can make them just as nice as the retail ones like mentioned for nothing, or whatever a few cotton balls cost you.
Another secret I posted in another thread. Sometimes, depending on climate, the humidor could harbor mold. You can tell if the cotton starts to get gray spots in it. To combat that, if you add a couple drops of Eucalyttus oil to the cotton. It keeps the mold at bay, AND makes your Uke smell nice...
