ENHANCEMENT OPTIONS

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. This special edition fountain pen has a deep teal blue aluminum grip section, cap ring, and piston knob. The aluminum is enhanced with a subtle matte finish, with 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.

By far, my favorite everyday pen!

Beautiful Pen

I love this pen. This is my very first fountain pen, and I don't think there is any pen more suited for an introduction to the world of fountain pens than this pen. I love that the mechanism is a piston, as it is so very easy to fill and clean out when changing ink. It is just beautiful to look at, the design on the barrel makes it look like the cuts on a diamond, hence the name. Also, the quality is remarkable. The materials that make up the pen just feel very durable and solid. It is worth every penny. It comes in a wonderful display case which is also inside a box, which just lets you know immediately that this pen is going to be remarkable.

Nice once the ink is in it

This is a satisfying pen to hold. Feels substantial in hand � if a little too plasticky. It's not heavy. And in general I think it is much more interesting to look at than I had expected when ordering it. It's certainly a fun pen. And it writes well enough. Is it perfect? No. I don't quite like its "sounds". There's something about the plastic that just doesn't make noises I like when handling a pen. Hard to explain this. It isn't the simple fun metal sound I enjoy from clicking my cheapo Parker Jotter. And it's a lot "noisier" than my cheaper Pilot Metropolitan � again a metal body that just doesn't make sounds when handled. The screw on cap gives me a lot of confidence that nothing bad is going to happen when this is jostling around in a backpack.

Great Pen

The Twsbi 580AL is a great pen, it is a great writer with good flow. This is actually my second Prussian blue 580. I had an accident with my first one that broke it, I liked it so much that I immediately ordered another one. As always Goulet Pen was fast to get the pen to me, fantastic company, been doing business with them for some time and will continue to do so.Ed Smith

Another great purchase

This is my second TWSBI, and it's as great as the first. As always, GPC is fantastic.

FAQs about Fountain Pens

How do I fill a fountain pen with ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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! 

What's your return policy? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

You can submit a return request within 30 days of your order date. You can read all our Return Policies here.

To initiate a return, please submit a request at the Return Portal. Our Customer Care team might reach out to you for more information.

Please note we are unable to accept a return of any Namiki or Sailor Bespoke fountain pen for any reason once it has been used with ink. Please thoroughly inspect and dry test the pen before use.
