TWSBI ECO Piston Fountain Pen

Cosmic Blue & Black Titanium

The TWSBI ECO series, created by the Taiwanese brand TWSBI, is highly regarded among fountain pen enthusiasts for its excellent value and reliable writing performance.

Equipped with a built-in piston filling system, the ECO offers a large ink capacity, reducing the need for frequent refilling. The pen features a German-made stainless steel nib, providing smooth and consistent ink flow for everyday writing.

Cosmic Blue

A deep, story-filled shade of blue. Rather than a single cool tone, Cosmic Blue blends night-sky navy, nebula-like soft purples, and subtly translucent teal hues. It feels as though the quiet vastness of the universe has been distilled into a single color.

With its understated sheen, this blue is both mysterious and gentle, evoking the slow movement of light and shadow in distant galaxies. Visually, it conveys a sense of profound calm while retaining a dreamlike, floating quality—an endlessly captivating color with a strong cosmic and futuristic character.

Black Titanium

Black titanium presents a dark, matte metallic texture—subtle, resilient, and distinctly modern. It forms a striking yet harmonious contrast with the flowing luster of Cosmic Blue.
