TWSBI Diamond 580ALR Fountain Pen - Sunset Yellow
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 sunset yellow 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 really like the texture on the grip, I know not everyone likes it but for me it's perfect long writing sessions.
Folks, it is difficult to fully express how glorious this pen really is! The pictures don't do it any justice!!! And it writes so smoothly - I didn't really know what to expect for a pen in this price range but thus far I am not disappointed. I'm still within my first week of using it but I have truly been using it - I have a state licensure examination coming up so I have had impressively long note-taking sessions with this pen and I still haven't used up my ink sample I purchased with it. I am hopeful this pen holds up to regular wear and tear, although I do catch myself babying it a little since the reviews I have found for it either really like it or really hate it; the latter is usually due to some kind of ease of cracking on the case (if it isn't a flow issue which I'm not worried about at the moment since it has written well for me for days now). Hopefully, it's a durable quality pen. I plan to adjust my review if needed as I continue enjoying this pen. Oh, and if you'd like a beautiful ink to pair it with, De Atramentis Document Ink Urban Sienna is a surprisingly (at least to me) good pair with the Sunset Yellow TWSBI Diamond 580-ALR! This was part of my "surprise me" ink sample pack and in the vial I really thought it was an ugly color. When my pen came in, I thought I'd use the ugliest ink first to test it but I was so pleasantly surprised with this ink on paper you guys!!!! It highlights the golden brown(ish) color of the pen so well ~ please try it! I simply can't describe it!
This store is my own person pens-R-Us. I can spend way to much way to easily because their website is easy to navigate. Their prices are budget friendly and the delivery always makes me smile, the sticker and candy is a fabulous touch that keeps me coming back
One of the best experiences on low budget. Very pleased with the purchase. Highly recommended! Confortable and soft.
This is my first fountain pen and I could not be happier with the purchase. I did a ton of research going into this and after being sick and tired of planned obsolesence and cheap junk, I decided to jump just above your typical starter pen. This pen has all the features that a beginner could want. It's easy to fill, easy to maintain, easy to write with, writes nicely and is made of robust materials! I paired it with a dark green ink and it looks amazing. Since this purchase I've grabbed several other pens from Goulet and I'll definitely be a returning customer.
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!
