Ink color: Black Mitsubishi Pencil's Signo retractable gel ink ballpoint pen. It's ultra-fine yet smooth. The newly formulated Signo ink and the elimination of the sharp tip reduce friction between the pen tip and paper, resulting in a smooth writing experience. This 0.38mm black ink ballpoint pen features an attractive one-motion design that hides the seam between the grip and barrel.
