The Luna Tattoo Concert Spruce ukulele takes its design from traditional Hawaiian body ornamentation—monochromatic and tattooed in black ink. The patterns and layout were strongly geometric and there were many shapes and symbols representing the natural island world: stones, waves, fish, sharks, turtles, rain, sun and birds. The design on the Luna Guitars Tattoo Concert ukulele is based on Polynesian tattoo style. The fret markers are stylized shark teeth. This concert ukulele boasts a clear, resonate sound both by virtue of its concert body and spruce construction.
