Brand: Mitsubishi Pencil Co.
Made in: Japan
Here is an unusual Japanese copying type pencil with eraser.....not so sure you can erase this type of mark, but whatever.
Founded in 1887 and formerly known as Masaki Yomato, Mitsubishi Pencil Co., Ltd. is best-known today for its uni-ball brand of quality writing instruments sold worldwide. Curiously, this Tokyo-based business is unrelated to Mitsubishi Motors and other brands within the Mitsubishi Group. Same name, same logo, completely different company.
