TWSBI Diamond 580ALR Fountain Pen - Prussian Blue
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.

Customer Reviews
This is my second 580ALR love the weight, the tank is huge and the nib writes smoothly
Very nice pen. Well made. It comes with a tool and instructions to disassemble the pen for cleaning or repair. I have 2 of the TWSBI Diamonds and enjoy them very much.
The pen is beautiful. I like the blue color.
The Diamond 580ALR is a brilliant pen. Nice grip section, good balance, wonderful ink capacity, brilliant writer. Goulet is my favorite pen and stationary online store. Wonderful service.
I'm a huge fan of TWSBI and I bought this one as a little treat to celebrate the completion of a huge project.
This one looks beautiful and feels great in the hand. And the nib lays down a nice amount of ink (I like it a bit on the wetter side) while staying very smooth. As a piston filler it holds a good amount of ink, so I have to fiddle around with my travel ink well a lot less.
By the way, Goulet pens had my little gift in my hands super fast.
