Hmm, they don't say anything about what it's made of, etc. Sounds like you could end up buying a kit for a uke that, when finished, would be lower quality than a cheaper lanikai or dolphin...
Looks like the "Grizzly" kit. It is a laminated bodied uke and not a bad kit. There is a company that custom-paints and finishes these ukes and sells them as custom-finished sopranos. They do a good job over-all, but, they sell at inflated prices.
