Pilot pen cases
The story of the birth of the Pilot brand is a fascinating one. In 1918, Ryosuke Namiki, then a teacher at the Tokyo Merchant Marine School, was dissatisfied with the writing and drawing instruments on the market and sought to improve them for his professional needs. So he made his first pen nib using gold for the body. Also he uses osmiridium (an alloy of iridium, osmium, ruthenium, platinum, rhodium and gold) for the tip. It was such a revolution that he created, with his colleague Masao Wada, a nib manufacturing company: the Namiki Manufacturing Company.
