The Kala Concert Ukulele is an affordable soprano uke made of sleek and attractive teak. Teak is a tropical hardwood that has a very soft brown color with tight, straight grain patterns and striping. It is known to be water resistant and durable, which makes it a great choice for any adventuring musician. The natural stain of the wood gives this instrument an organic and fresh-cut feel that is right at home in the outdoors.
