This is a multi-function pen from Mitsubishi Pencil, the uni Jetstream, which combines a 4-color ballpoint pen (black, red, blue, and green) with a mechanical pencil. Although unused, there is a crease as shown in the third photo, which occurred when I took it out of the box for the photos. I am selling it because I have no plans to use it. Would it be suitable for everyday use, or as a light congratulatory gift for passing an exam or graduation?
