Beautiful red and blue version of this piston-filler pen


The 580RBT Is The Returning Red-Blue TWSBI Diamond

TWSBI make fountain pens for enthusiasts, no cartridges are used and tools are supplied for servicing your own pen. Not the cheapest but beautifully made and distinctive to look at.

The TWSBI Diamond 580 Fountain Pen RBT (which stands quite simply for red and blue) features a transparent barrel enabling you to see the ink inside. No need for cartridges or a converter as this is a piston-filler - simply retract the piston to pull ink in to the barrel. The pen is finished with a chromed metal trim and pocket clip plus the red TWSBI logo on the cap top.

The polished steel nib is engraved with TWSBI logo and branding and the pen comes in a range of nib sizes: fine, medium, broad, extra-fine, and stub 1.1mm. The cap and end are hexagonal so the pen won't roll when the cap is on or posted and it 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 should you wish to have a go but it should not be necessary for normal use.

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.
