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.

This pen features an aluminum grip section and piston mechanism. It 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!

Quite possibly the smoothest...

Quite possibly the smoothest extra-fine fountain pen I have ever used! I have always been a fan of extra-fine pens due to my penmanship (or lack thereof) and my habit of jotting things down in pocket journals like Moleskeins or Rhodias. I have used Lamys, Pilots, Kaweko Lilliputs and others, but they all come off as scratchy, not smooth. Medium points are smooth but too fat for my taste. That was until I got my mitts on the TWSBI Diamond 580AL Extra Fine. This pen, loaded with Pilot Shin-Ryoku Iroshizuku ink (in green, of course) lays down a silky smooth very fine line in my Rhodia Pocket Journal. This pen is a demonstrator/skeleton style meaning a clear plastic body exposing all of the pen's inner workings to the world. However, they pen has a nice heft to it that help me keep it nice and steady. This is by far, the best fountain pen you can buy for the price. Period.

After 2 weeks of use, I'm very happy with this pen. Flow is superb, and the nib is one of the better ones I've used (though I haven't gone over $200 on a pen yet, to give you an idea of my basis for comparison).

I like that the built-in converter has easy access at the bottom of the pen (you don't have to open/unscrew anything to adjust it). But ...

I took away 1 star only because the converter feels kind of loose. It has a little bit more of a give than I would like. Granted, said give doesn't push/pull the piston, so it's not that easy to accidentally adjust it without intending to, but it does take a way a little bit of my confidence in the pen's integrity.

That being said, this flaw is not enough for me not to like it.

I have been using it constantly since I bought it, exactly a month ago, and I am not disappointed in the slightest. I can now say it was quite the investment. The Diamond 580 is only the 3rd fountain pen I've ever bought, and it is much better than my last two. I always bring it everywhere and use it for note taking, studying, work, and anything really, and it has done me nothing but wonders.

It refills very nicely with my Bernanke Black Noodler's Ink. The refilling process is very easy, and probably much more cost effective than using cartridges, which is what my last two pens used.

If you can't tell from the picture, the pen looks amazing. The AL is a very beautifully designed pen. The AL has a metal grip and metal piston system, as compared to plastic. I would recommend just getting the AL because it looks great and is only a little more expensive. Might as well go all the way, right? I really love the clear body concept, as well as being able to see the ink. You can easily see when you're going to run out, which is good if you can't carry a bottle of ink around everywhere. The clear body is textured with facets, as if it were a diamond, and can sometimes reflect some pretty lights. If you use the pen in public, expect to get a lot of attention from people, because I sure do.

Writing with the pen is very smooth and the ink flows from the nib well. I have had no problems with the nib scratching paper or anything like that. The weight and size of the pen is just right for me, and I have medium sized hands. Sometimes my hand gets tired from writing for longer periods of times, but that is mostly because I have to switch from my usual writing position to one suited for a fountain pen, which I am not used to.

I would definitely recommend this pen to anyone. It's easy and fun to use, and I feel great writing with it. Sure, it's a little pricey, but it is definitely a worthy investment, and actually quite cheap when compared to some other fountain pens.

Incredibly well-made pen for the price. The EF is just a tiny bit broader and wetter than a Lamy EF. I had originally purchased a 580AL with an F nib and the nice folks at JetPens allowed me to return it when the pen was abnormally (ridiculously) wet. The EF replacement is perfect.

I tried this pen and nib combo with the J. Herbin Stormy Grey ink and it was not a good match. The ink dried too fast and rendered the pen useless. I'm going to try the same ink with fine and medium nibs to see if I get better flow out of this ink.

On my second try I used an Iroshizuku ink and the flow was so much better--cleaner, legible, and smooth. The pen itself is pretty cool. This is my first demonstrator pen and being able to see the mechanical features of the pen, along with the amount of ink remaining is pretty cool! The piston-type filling system is easy to use too.
