Caribbean + Onyx - Diamond 580 - TWSBI Fountain Pen

580 has increased ink capacity, about 30% more than 530

580 has improved the smoothness of cap thread turning

TWSBI Diamond 580, a classic fountain pen with a piston ink-filling system. By fusing the traditional mechanisms of the fountain pen with a modern industrial design, we have created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present. The Diamond 580 comes with a benchmark ink-filling mechanism and has all detachable parts. We felt that it was important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen.

Fill Mechanism: Piston Filler

Pen cap is able to post onto the back of the pen

How to fill: 
Simply unscrew the end cap, dip it into the ink, screw it back on, and you're done! Ready to write!

Pen cap has an inner cap to ensure a perfect seal when stored away. 
Made for the beginner who just wants to try out fountain pens, all the way to the experts. A good everyday worker.

For the normal writer, Fine (F) is the most popular
If you tend to lean on a bigger font, Medium (M) will be perfect

Please note: Ink is NOT included. We recommend pairing this with a water-based, non-shimmer ink.
