Brand: Mitsubishi Pencil Co.
Made in: Japan
Older version of the uni star F. Pencils are still being made today only with the barcode on the reverse not the older JIS mark as shown.
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.
