TWSBI Diamond 580ALR Fountain Pen - Nickel Gray
The TWSBI Diamond 580ALR comes with a benchmark piston ink-filling mechanism and has all detachable parts. The clear demonstrator barrel allows you to see your ink color and remaining ink level. It has a silver aluminum grip section and screw-cap. The aluminum is enhanced with a subtle matte finish, and circular engravings in the grip and cap area. It comes with a stainless steel nib and is presented in a modern clear display case.
The idea behind the TWSBI Diamond 580 was to go back to basics and capture the simplicity and elegance of traditional writing instruments. In recent years, the development and modernization of writing instruments has resulted in traditional writing instruments, such as fountain pens, falling into obscurity. It was TWSBI's goal to bring the past back to life by creating a traditional fountain pen that even modern day society can appreciate.
The TWSBI Diamond 580 is a classic fountain pen with a piston ink-filling system. By fusing the traditional mechanisms of the fountain pen with a modern industrial design, TWSBI has created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present.
TWSBI's belief is that it is important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen. These pens also come packaged with a wrench and silicone grease. Neither of these accessories are intended to be used immediately, as they are for long-term care and maintenance. Additionally, please use extra care if you choose to disassemble the nib and feed, as the feed is very fragile.
You may notice a white substance on your 580AL or 580ALR pistons. This is bearing grease, and must not be removed during cleanings, or replaced by silicone grease.

Customer Reviews
I purchased the black Eco in Fine and liked it, but was curious about the Diamond. I was also interested in trying a finer nib. I tend to write more legibly with EF nibs from western brands. TWSBI offers a plethora of colors to choose from. I reasoned that I'd want to match the pen color with the ink in most cases and thought that silver would go well with any color. I've found that TWSBI's tend to write a bit more wet than some of my other pens, and I have more letter control writing with the EF compared to my Eco F nib. The pen looks and feels premium-like something out of a futuristic movie. My only critique would be on the grip section. The silver version can feel a bit slick. While I haven't had issues with it, I do wish I would have tried the grooved version (ALR)-maybe next time. Overall, it's a great pen and I'm happy I bought it. If you like the Eco, you'll love this one.
I want to conclude with my Goulet Pen experience. I've made two purchases so far. I really like that they sell ink samples. Each time my order was shipped promptly and I received my items quickly. I will continue to purchase from Goulet. Happy customer.
Love this pen, the gray is darker then it seems on the pictures
High quality, substantial build, beautiful finishing and yet no pretense of luxury! I've been very pleased with the purchase of this pen. TGPC shipped quickly & everything arrived well-packaged and safe!
I would rather have a broader, wetter nib, but most of my writing is on cheap copy paper at work. The extra-fine is perfect for this. I can feel a bit of feedback, but this pen is pleasant to use. I am using Kon-peki ink and find the combination suits my needs perfectly.
I am in my honeymoon phase with fountain pens, and Goulet Pens has become my go-to source for podcast knowledge/advice and quality products at good prices. Inks are cheaper to buy than pens, so I have now bought 4 TWSBI Diamonds because of the ease of swapping in and out new inks with the easy to use piston filling mechanism. I have a Fine and 3 Medium nib Diamonds and find the Mediums to be just about perfect for me in terms of ease of writing with enough ink output to be able to see some of the ink shading. The Fine nib is also terrific, but I find myself using it almost exclusively now with a Noodler's Black ink for everyday writing. Everything "fun" is the 3 Medium nib Diamonds with a variety of bottled inks...
FAQs about Fountain Pens
How do I fill a fountain pen with ink?
It depends on the pen's filling mechanism, which you can find in the Technical Specs section above.
Here's a quick definition of the most common filling mechanisms:
- Cartridge - A small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write! Check out our quick guide here.
- Converter - A detachable and refillable ink reservoir that allows you to use bottled ink in a cartridge-accepting pen. Typically you will install the converter into the grip section, dip the nib/feed into the ink, and twist or pull the converter knob to draw ink into the converter. Here's a video for how to fill a cartridge/converter pen using a LAMY pen as an example.
- Eyedropper - A pen that utilizes the entire barrel as a reservoir for ink. Ink is directly filled into the barrel, allowing for a high ink capacity. Here's a video on how to do it!
- Piston - A type of filling system that uses a retracting plunger inside a sealed tube to draw ink into a pen. They are typically either twist or push-operated. These pens cannot accept cartridges or a converter, and only fill from bottled ink.
- Vacuum - A push-style piston that uses pressure to fill the large pen body with ink. They seal the ink chamber when closed, making it ideal for flying without risk of leaking. Check out our video on how to use a vac filler here.
Check out more info on these filling mechanisms including a video on how to fill each one on our blog.
How do I clean a fountain pen?
It depends on the filling mechanism, but it mostly comes down to flushing it out with water, and sometimes a little bit of Pen Flush if the ink is really stuck.
It's a bit easier to show than to tell, so we've put together a few quick videos showing you the process:
How often do I need to clean my fountain pen?
We recommend a good cleaning every 2 weeks, and any time you change ink colors.
Water will usually do the trick, but we recommend you use our Goulet Pen Flush if the ink has been left in the pen for a while and could have dried up, or when you’re switching ink colors.
My pen won’t write! What do I do?
First things first... make sure you have ink in the pen! Be sure that the ink cartridge or converter is seated properly in the pen, and that you aren't out of ink.
We always recommend you give your pen a good cleaning first, using our Goulet Pen Flush, or a drop of dish soap in some water. New pens often have some machining oil residue left in the feed, so a good cleaning often does the trick first.
If that still doesn't work, try priming the feed. This consists of either dipping your pen nib and feed in ink, or forcing ink from the converter down into the feed.
If it’s still not working after that, please reach out to us so we can help!
