This is a mug shaped like a Tiki with sharp triangular teeth and a nose ring. He is also holding a tattoo machine. Marked "Naked Steel" vertically down the back. Naked Steel is a Tattoo Parlor in Zofingen, Switzerland. Their T-shirt logo was designed by Mr.G.of Japan. Jan Kaegi designed this Tiki mug based on that logo. This version is custom, and glaze colors and details vary.
