Dive deeper into your thinking

The TWSBI Diamond 580ALR Caribbean with Onyx trim combines a vibrant teal-blue body with dark black accents that shift the mood away from playful and towards focused. The darker trim pushes the colour deeper into the blue spectrum, making it easy to pair with everything from turquoise and navy through to warm amber inks.

Built on the reliable Diamond 580ALR platform, it combines high ink capacity, a smooth wet stainless steel nib, and a more refined grip design.

What sets it apart

Piston filling system, with high ink capacity
Turquoise/black visual appeal, easy ink matching

Feel in the hand

FAQs

Is this beginner-friendly?
Yes, you dial in the ink at a controlled pace, and will be writing for a couple of weeks before you have to refill. The pen box includes filling instructions.

How much ink does it hold?
The chamber can hold up to 1.9mL, which is 2-3 times a cartridge or converter.

How does it compare to Twsbi Eco?
The Diamond 580ALR feels more developed, with a more comfortable grip, aluminium components, and screw-in nib units. Eco is the simpler, more economical version.

What's the difference between 580, 580AL and 580ALR?
The 580 is the base model of the Diamond series. The 580AL upgrade includes more aluminium parts and the 580ALR also includes ribbing on the grip. Most new releases are in ALR.

How does Caribbean colour way compare to the Prussian Blue?
Carribean is brighter, fresher, more teal leaning. Prussian is traditional, a deeper blue, and feels more controlled.

Can you change nibs?
Yes, the nib unit is replaceable and can be changed on the pen even when the pen is inked.

Does it come with ink?
No, bottled ink is required. You can use any bottle ink labelled suitable for fountain pens.

Is it fragile?
Not with normal care. Avoid over-tightening the cap and minimise unnecessary disassembly.

How do you clean it?
Routine cleaning only requires you to expel the old ink and cycle water through the nib/barrel a few times before refilling. Disassembly for piston regreasing is only needed long term, and only if the piston becomes stiff.
