TWSBI ECO Fountain Pen / Black Marble and Bronze

The TWSBI ECO fountain pen is a true workhorse that’s made for everyone, from the beginner who just wants to try out fountain pens, all the way to seasoned fountain pen experts. Taking different design cues from the TWSBI Diamond 580, the ECO features a postable cap for maximum versatility. The pen also has an inner cap to ensure a perfect seal and prevent the nib from drying out when not in use.

The “Black Marble + Bronze” ECO is part of TWSBI’s Mixed-Color series, where different resins are mixed into the injection molding process to create truly unique color combinations. No two pens will look alike, as each will haver its own unique swirls and patterns. This pen’s colors features swirls of black, grey, and white, paired with TWSBI’s bronze trim.

Please note that the TWSBI ECO fountain pen is a piston filler, and only accepts bottled ink.
