The story
Most of the fountain pens had been made of ebonite, a material that combines sulfur and rubber. However, ebonite changed color and lost its shine as the years went by. Being aware of this, the Namiki Co. Ltd. (current "Pilot Corporation") started to try different methods and materials to overcome the problem. After some attempts, they discovered that lacquer coating could tolerate deterioration and make pens more durable. They also tried painting designs on fountain bodies, using the maki-e technique, The process would be later patented by Pilot.
In 1925 the Namiki brand was launched to market, with lacquer artists Shisui Rokkaku and Gonroku Matsuda invited to make fountain pens. Ryosuke Namiki and Masao Wada (founders of Pilot Co. in 1918) traveled to promote their maki-e pens in Western countries. In 1926, a Pilot Office was opened in London, England, and four years later a contract was signed with the Alfred Dunhill Ltd. to commercialize Namiki pens in the main European cities and the United States under the brand "Dunhill-Namiki Made in Japan". The brand would later expand to New York, Shanghai and Singapore.
