Brand: Mitsubishi Pencil Co.
Made in: Japan
The old JIS or Japanese Industrial Standards symbol on the reverse (was used until September 30, 2008). This pencil can now be found today with a barcode.
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.
