The TWSBI 580 Diamond (or more commonly called the 580) is a classic demonstrator fountain pen that utilizes a piston mechanism. It is an upgrade from the former 530 and 540 versions. The elegance and simplicity of this pen makes it stand out from our modernized writing instruments.

*The 580ALR model is a variation that features a matte aluminum grip section, connector and piston rod.


  • Improved grip and end barrel section compared to the 540
  • Increased ink capacity, about 30% more than the 530
  • Smoother threads that makes removing or putting the cap back on easier
  • Secured screw-on cap to prevent accidental leakage
  • The pen can be completely disassembled for easy cleaning
  • Can easily refill using the TWSBI Diamond 50 ink bottle

Tips on choosing a nib size:

  • EF = perfect if you tend to write small
  • F = for a normal writer, F is the most popular option
  • M = if you tend to write in bigger font, M will look good
  • B = not your everyday writer, but great for making a statement or for signatures
  • 1.1mm Stub = got a special card or invitation to write? This is the nib that allows you to write in a fancy italic style.

TWSBI is a well-known pen manufacturer based in Taiwan. Their goal is "to inspire and recapture the romanticism of art and literature... starting with the pen".

Top Notch Pen

The purple aluminum is just beautiful on this pen. A very solid, quality, well built product. The fine nib is extremely smooth and nicely wet. It does got scratchy and unpleasant for reverse writing, with certain inks. For the price, this pen is hard to beat. Absolutely pleased with this writer and seller. Delivery was fast and I will certainly purchase from them again.
