Twsbi Diamond 580 Fountain Pen - Iris
Although relatively new to producing their own line of fountain pens, TWSBI has been in the industry for half a century, creating parts for other brands under the name Ta Shin Precision. Within a decade, their piston-filled demonstrator pens have become immensely popular for their high quality, large ink capacity, and affordable price point which allows many newer fountain pen users to get their hands on a remarkable pen very early into the hobby.
