Brand: Mitsubishi Pencil Co.
Made in: Japan
I haven't seen this one before. The erasers a bit used, and there is an ink stain on this one, but better than nothing.
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.
