TWSBI Diamond 580ALR — Prussian Blue | Medium Nib | Piston Fill
The TWSBI Diamond 580ALR in Prussian Blue is a stunning evolution of one of the most beloved pens in the TWSBI lineup. The ALR designation brings an anodized aluminum grip section — smoother, more durable, and more refined in the hand than ever before. The deep Prussian Blue finish is rich and commanding, giving this demonstrator pen a personality as bold as its performance.
The steel medium nib writes with the confidence and consistency TWSBI is known for — smooth, well-tuned, and perfectly suited to everyday writing and journaling. The piston filling mechanism holds a generous ink capacity, keeping you writing longer between fill-ups.
A favorite among fountain pen enthusiasts who want outstanding performance, striking aesthetics, and a pen that's built to last.
Complete the experience with Pilot Iroshizuku Kon-peki — a rich, saturated deep blue with a hint of teal in good light, made in Japan by Pilot and named after natural Japanese landscapes. Paired with the Prussian Blue barrel, it's a combination that feels entirely intentional.
