You wouldn't guess it from the name, but Ortega are a German ukulele manufacturer. They are primarily a classical guitar company (they've been making them since 1996) but have a range of 6 ukuleles.
The only place I've seen this ukuleles for sale is on Thomann, but I've used them a couple of times and they're a reliable company. I live in the UK and they delivered quickly. My only complaint was the shipped a lone thumb pick in a box big enough for a bowling ball.
The RU10 is Ortega's entry level uke. But it's solid mahogany so a step above most company's beginner ukuleles.
Construction: Solid mahogany top, back and sides
Fretboard: Sonokeling (apparently, it's a cheaper relative of rosewood)
