DescriptionSpecificationsQuestions & Answers (5)
TWSBI fountain pens are loved for their high quality and affordability, offering advanced filling mechanisms normally reserved for much more expensive fountain pens. The TWSBI ECO (short for "economical") provides the same high-quality, high-capacity piston filler as the TWSBI Diamond 580 at an even lower price. It features a sleek, transparent barrel and a hexagonal screw-on cap that can be posted securely on the back of the pen. The piston filling mechanism is easily operated by twisting the knob at the end of the barrel counter-clockwise to extend the piston, submerging the nib in ink, then screwing the knob tight to retract the piston, drawing ink into the pen straight from the bottle. There's no need for cartridges or a converter! Be careful—operating the piston while ink is in the pen will cause ink to leak out of the pen.

This limited-edition pen features an indigo blue cap and piston knob, accented with a bronze-colored nib and trim.

In keeping with their philosophy of promoting the traditional experience of using a fountain pen, TWSBI has designed this pen to be completely self-serviceable. It comes with a wrench and a vial of silicone grease you can use for at-home maintenance.

Notes:

  • TWSBI pens with rose gold or bronze nibs may write broader than their silver nibs.
  • Some TWSBI ECO Fountain Pens have nibs and feeds that are very difficult to remove. Attempting to remove the nib and feed forcefully may damage the feed.
  • This pen only uses bottled ink, which is not included with this pen. Check out our collection of bottled fountain pen inks here!
  • This pen may come with ink residue in the nib from being dip tested by TWSBI at the factory. As with all new fountain pens, JetPens recommends giving your TWSBI a good cleaning before you use it.

Beautiful and lovely pen to hold and look at, but I'm a bit disappointed by the nib, which appears closer to M, judging by the sample handwriting test in the product description. Maybe I will have to look for a different ink, as others have mentioned in the reviews.

Gorgeous pen and the EF nib is the smoothest fine tip I have used yet. This is the most reliable, comfortable and beautiful pen I've yet used.
