Thank you for viewing. This is the Mitsubishi Pencil mechanical pencils, "M5-301" and "M5-201". I am selling these to organize my collection. Both feature a triangular grip. Neither of them had a specific name, and the product name is "Sharp". ○ M5-301 The color is vermilion, and the grip is gray. It has a fixed tip, and the clip is made of metal. There is some deterioration in the plating. ○ M5-201 The color is red, and the grip is blue. It has a fixed tip, and the clip is made of resin. Judging from the specifications, this seems to have been a cheaper version of the 301. I think this 201 is rare because I couldn't find the same one even after searching. The eraser is unused. Operation has been confirmed. These are discontinued pens that are no longer in production. Model Numbers: M5-201 M5-301 uni ※ These are 0.5mm mechanical pencils. Please be careful not to make a mistake. #Shiro's Stationery We also offer combined sales. For those who understand, Thank you. Type...Mechanical pencil body Lead/Darkness...HB Body Material...Plastic
