Brand: Mitsubishi Pencil Co.
Made in: Japan
Three different sizes of the uni HB. The Jumbo-uni is circa 1985. FYI: The middle pencil is the standard size. The bottom is tiny. Interestingly enough each one of the Jumbo uni's say 85th “Thanksgiving” Anniversary on the reverse. NOTE: The standard uni with JIS mark in the middle is available for purchase.
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.
