In order to create a masterpiece that would make a statement when placed in a breast pocket, we took on the challenge of manufacturing a fountain pen in Gunma, a prefecture with a concentration of precision machining masters. Gunma is a pen-producing region with many factories run by famous writing instrument manufacturers. The nib is a 14-karat gold nib from Sailor fountain pens, which is highly acclaimed worldwide for its comfortable writing feel. We will continue to work with artisans to create pens that captivate writing instrument fans around the world.
