Head office is based in Tokyo, Japan. Mitsubishi Pencil's "uni" brand was derives its name from the word "unique". Mitsubishi Pencil's extensive product variety is indicative of its desire to create products that uniquely match the needs of individual users. A case in point is the pigment ink we use for roller balls, ball-point pens and markers. After many experiments to accomplish superior water
and fade resistance, while ensuring satisfactory colour brightness and writing performance, Mitsubishi Pencil established the Ultra Particulate Pigment Dispersion Technology. This technology real-ises product excellence as exemplified by the "uni-ball Signo" series. Furthermore, carbon processing technology cultivated by pencil manufacturing has evolved into original new carbon manufacturing technology, known as PFCT (Plastic Formed Carbon Technology). PFCT can carbonise through moulding similar to plastic, and is utilised in the production of mechanical pencil leads, ensuring high intensity and smooth writing performance. To deliver still higher product quality at reduced cost, Mitsubishi Pencil has been engaged in a process of rationalisation, elimination and automation. Mitsubishi Pencil's high-speed, automatic precision machinery and inspection devices are widely regarded in the manufacturing industry. Aiming to establish a smooth distribution network worldwide, the company has developed production bases in the US and China, and has also established affiliates in the UK, Singapore, Spain, Taiwan, Australia, Hong Kong and Korea. The history of the company began with the manufacturing of pencils and has progressed to the development of various high technologies. In many countries throughout the world, Mitsubishi Pencil's products proudly uphold the "uni" brand name.
