TWSBI fountain pens are loved for their high quality and affordability, offering advanced filling mechanisms normally reserved for much more expensive fountain pens. The Diamond 580 features a modern, eye-catching design, with a transparent body that shows off the pen's inner workings. Its faceted barrel catches light and makes your ink shine, and it also helps keep the pen from rolling away. The high-capacity 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 can be refilled from any fountain pen ink bottle, but for clean and easy refilling, try a TWSBI Diamond 50 Ink Bottle, which has a special component designed specifically for refilling TWSBI Diamond fountain pens.

The pen comes in an attractive clear plastic case with a clean, modern design.

For protection, the plastic case is packaged in a cardboard box. This cardboard box is fragile and may get crumpled during shipping.

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

For the money I do not think you can find a better fountain pen. Made very well and as good as or better than more expensive pens I have. Love it.

For $50.00, steel nib is so highly polished it writes as smoothly as 14 caret gold nibs I own at over $250. Best value ever!

It comes apart - completely. It puts back together. It sucks ink from its companion bottle, and it lays it down on paper without so much as a tap - *on the first inking*. The nib has a little tooth to it, but it's *pleasant*... and it's got that internal seal in the cap so you can leave it sit for who knows how long and come back and pick it up like an abandoned ballpoint and it still lays it down pretty as you please. I wish I had the kind of dosh to throw around to make this my EDC pen, because it's that nice. As it is, I don't want to leave it somewhere... so it has pride of place on my desk.

The only downside I can say for this pen is the amount of ink it holds. If you use this semi-regularly don't fill it more than half because this hold so much ink. Never worry about whether your ink is low. Because there's always enough ink in my opinion.

I used to not like this because the Fine wasn't as Fine as my Pilot Met, but the more I use it the more I realize I like this Fine over Pilot's. All my inks flows super well and it's very cool looking.

I don't own an ECO, but I can say that I'm glad the ECO I wanted was out because this pen is so worth it. If you post your pens, I wouldn't recommend this. It can get messy since it posts on the piston and it makes the pen back-heavy (weight tilts away from the nib)
I don't post so I don't have this problem.
