Kaweco Supra Fireblue Fountain Pen

The Kaweco Supra Fireblue Fountain Pen is where engineering meets alchemy. Made from solid stainless steel and individually heat-treated by flame, each pen displays a unique spectrum of blues, purples, and copper tones—no two are alike. The result is a fountain pen that feels industrial and organic all at once.

What sets the Supra apart is its modular design: a removable centre extension allows you to switch between a compact and full-length pen. Fitted with a #6 stainless steel nib, it offers a smooth, assertive line and excellent balance in either configuration. Over time, the Fireblue’s surface continues to evolve, developing its own one-of-a-kind patina.
