Brand: Mitsubishi Pencil Co.
Made in: Japan
The grade is between Hi-uni and uni. 1970's or 1980's. This has to be one of the heaviest gold foiled embossing work ever!
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.
