Discover the TWSBI ECO Cosmos Blue & Onyx, an elegant edition inspired by the mysterious depth of the night sky and the fascinating beauty of the universe. Its refined design with deep nuances evokes the colors of the cosmos and brings a modern and sophisticated touch, ideal for fountain pen enthusiasts looking for a writing instrument that is as high-performing as it is aesthetic.

The Onyx-colored finishes – nib, clip, and rings – create a remarkable contrast with the pen's tones and reinforce its contemporary character. Its transparent barrel, emblematic of the TWSBI ECO collection, allows for easy monitoring of ink level and color, adding a practical dimension to its unique design.

Each fountain pen in the TWSBI ECO Cosmos Blue & Onyx collection is unique. Thanks to its specific manufacturing process, no two models are identical. Some pens may have deeper or lighter shades of blue, while others may reveal more white touches or even slight green nuances. The patterns, intensities, and color blends vary from one pen to another, making each piece a writing instrument with its own visual identity.

Equipped with an Onyx-colored steel nib, this fountain pen offers smooth, fluid, and precise writing, ideal for daily notes, long writing sessions, or creative work. Its integrated piston filling system ensures a large ink capacity and a comfortable, uninterrupted writing experience.
