Brand: Mitsubishi Pencil Co.
Made in: Japan
Rare and hard to find in good condition. Most I've come across have cracks in the paint that are lifting the paint and causing it to flake off.
Founded in 1887 and formerly known as Masaki Yomato, Mitsubishi Pencil Co., Ltd. is best-known today for its “uni” 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.
