A symbol contour is formed in a first position on the perimeter of the ink stick body. The symbol contour defines a portion of a perimeter of a visually recognizable symbol shape and extends at most partially along the perimeter of the ink stick in the longitudinal dimension of the ink stick body. At least one key contour is formed in a second position on the perimeter of the ink stick body corresponding to a color of the ink for the ink stick body.
