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—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.

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.

This pen only uses bottled ink, which is not included with this pen. Check out our collection of bottled fountain pen inks here!

This is my third TWSBI fountain pen. I have the 580 Diamond, the Mini and this one, all in EF nib. All write equally well using Pilot Ama-Iro Iroshizuku ink. My Mini experienced a small ink leak that was corrected with the application of the included silicone grease (don't ever throw out the pen box!). The ECO model has a smooth barrel vs the faceted one of the Diamond. The pen cap screws on the front but clicks on the back when it is posted. This is very nice for those with OCD who like to have the pen clip line up with the top of the nib (like me). The balance of the ECO pen when posted is much better than the 580 Diamond (too heavy) or the Mini (lighter, but the clip never lines up with the nib). If you want a great pen at a great price the TWSBI ECO Fountain Pen is the one you want to order!

I love this pen. It writes smoothly and has no problems starting even after a couple of days of non-use. The pen holds a large capacity of ink, so it is great for doodling for long periods.

Fantastic pen for the price. Nib not as extra fine as on my more expensive pens, but still a nice line. Ink flows first time even after not using for several days, which is a big plus. I would definitely purchase again.
