TWSBI Eco Fountain Pen, Black Marble
The TWSBI ECO fountain pen delivers exceptional value with a smooth piston filling system at an accessible price point. It features a crystal-clear acrylic barrel so you can easily see your ink level, paired with a marbled black cap and finial. An inner cap helps create a tight seal when the pen is stored, while bronze PVD trim and a matching stainless steel nib complete the look.
The Black Marble finish is created using a specialized injection-molding technique that produces unique patterns and color variations—no two pens are exactly alike!
Piston Filler Fountain pen
Simply unscrew the end cap, dip into ink, screw back the end cap, and you're done! Ready to write!
True to TWSBI’s philosophy, the ECO is designed to be fully disassembled and reassembled, letting users experience the mechanics of a traditional fountain pen. Each pen includes a wrench and silicone grease for long-term maintenance; these tools are not meant for immediate use. If you choose to disassemble the nib and feed, please handle with care, as the feed is delicate.
