Beautiful red and blue version of this piston-filler pen


The 580 RBT Is The Returning Red-Blue TWSBI Diamond

In this edition, the The TWSBI Diamond 580 RBT (literally meaning Red-Blue TWSBI) has the Taiwanese blue and red colours present in the semi-transparent cap and piston end.

The TWSBI Diamond range brings along a faceted barrel, leading to the "diamond" name as it adds a more spectacular look. A sleek tapered pen cap ends with the TWSBI badge embedded as a jewel in the crown.

TWSBI make fountain pens for enthusiasts, tools are supplied for servicing your own pen. Beautifully made with a distinctive look brought to you from Taiwan.

No ink cartridges are required for the TWSBI 580 RBT, ink is drawn straight in to the clear barrel. The pen comes in a gift box with a special spanner and silicon grease so that you can disassemble the pen and maintain it yourself. A leaflet is provided with servicing instructions if required. This isn't required for a normal cleaning routine but if your pen requires a more thorough clean then these help to disassemble your pen.

Key features:

  • Piston filler pen - no cartridges or converter needed
  • Takes any good fountain pen ink (KWZ should not be used as it reacts with the grease)
  • 141mm long cap on, 130mm long cap off, 176mm long cap posted. 
  • Comes in a gift box

Is Medium nib comparible with M nib from Lamy Safari?

Question submitted by: Anne Dequidt on: 2017-05-01 20:46:43

Bureau replies: these two nibs are very similar. Lamy may be a little bit broader than TWSBI.
