Thank you for viewing. This is a Mitsubishi uni 0.5 super mechanical pencil. It features a now-rare etched barrel, combining design and practicality, with ink inlaid in the engraved logo and Mitsubishi mark. This is a wonderful pen that shows a real attention to detail. It is now discontinued and difficult to obtain. I'm offering it to those who like Showa retro items or those who appreciate practical pens. The stainless steel processing is very meticulous, and the construction, which involved considerable cost, has a charm that is not found in recent resin pens. The stepped design of the pen tip is also excellent, and the metal barrel makes it durable, feeling like a pen that will last a lifetime. It's in good condition considering its age, but please understand this before purchasing. m(_ _)m
