is a privately-held Japanese manufacturing company of stationery products. The name is a combination of the English words pen and tell (as in, telling a story). Pentel is also the inventor of non-permanent marker technology. Most Pentel products are manufactured in Japan, Taiwan, Korea, Mexico, and France. The company is regarded as the inventor of the fibre-tipped (felt-tip) pen in 1963. Nowadays, Pentel produces a wide range of products that include writing implements, art materials and office goods. History The company was founded in 1946 as "Japan Stationery Limited" in Tokyo by Yokio Horie, with the purpose of manufacturing crayons and pastels. The first products for sale were released in 1951, followed by pencils in 1960. In 1963 Pentel launched the "Sign Pen", a fibre-type pen that was used by then President of the United States Lyndon B. Johnson, who bought a dozen of them to sign photographs, apart from being adopted as the official writing instrument of NASA and going into space with a Gemini mission in 1966. Demand for a Sign Pen was so extraordinary that the Tokyo factories could not supply all requests. The Sign Pen was one of Pentel's most successful products with more than two billion units sold. In 1971 the company changed its name to "Pentel Co. Ltd." and one year later, the green rollerball pen with water-based ink, was launched. Horie remained as President of the company until his death in 2010. In the 2010s, Pentel launched the "Pocket Brush", a fudepen that used replaceable waterproof ink cartridges, like fountain pens (and unlike conventional brush pens, which are more like marker pens.) Brush pens (designed and recommended for calligraphy) have also gained popularity among comic book artists, who choose them to ink their works instead of dip pens or traditional brushes. One of those artists using Pentel was Neal Adams.
