Product Features:
Make you more like me than now. KOKUYOME series 2-way marking pen.
      The thick side is a soft colored ink that does not flicker, making it suitable for 
      marking from the top of letters, and the thin side is a dark colored extra-fine pen that 
      is suitable for memorizing important information.
Two types of marking can be done with one pen case, so the pen case is not bulky.
