The TWSBI Eco Cosmo Blue with Onyx fountain pen expands the iconic Eco collection, renowned for its balance of quality, functionality and contemporary design. This special edition stands out with a cosmic blue cap, enriched by swirling tones reminiscent of glowing galaxies and shifting light.
The translucent turquoise end cap adds a fresh and vibrant contrast, while the onyx-black ruthenium trims – clip, rings and nib – bring a refined and modern look. The clear barrel allows you to easily monitor ink level and color, enhancing both practicality and visual appeal.
Equipped with a steel nib and a reliable piston filling system, the TWSBI ECO delivers smooth, consistent writing with a generous ink capacity perfect for everyday use.
As with all TWSBI fountain pens, the ECO Cosmo Blue with Onyx is fully disassemblable for long-term maintenance. The package includes a wrench and silicone grease, provided for pen care and not intended for immediate use.
A vibrant, modern interpretation of the ECO series, inspired by color, light and the beauty of the cosmos.
