Gallery image shows front and reverse of two older variations of the Mitsubishi 9800. The top older model says Patented and the bottom model says Matured. Also the writing on the reverse is different. NOTE: The top Patented model is available for purchase.
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.
