The Luna Concert Tattoo Mahogany is a traditional concert ukulele that takes its design from traditional Hawaiian body ornamentation. Those designs were monochromatic, tattooed in black against brown skin, with strongly geometric patterns, and many shapes and symbols inspired by the natural island world: stones, waves, fish, sharks, turtles, rain, sun, birds. Luna's design is primarily based on waves and sharks teeth which are also echoed as fret markers.
