TWSBI Diamond 580 Fountain Pen with Smoke Grey cap and barrel end, and Rose Gold trim. Transparent barrel reveals the filling mechanism, a built-in piston-filler with a very smooth action. Polished rose gold trim and pocket clip. TWSBI logo nicely finishes the top of the pen's cap. Rubber o-ring on cap thread ensures an airtight seal to prevent ink drying out in the pen, whilst also ensuring that the cap is firmly attached to the pen when not in use.

Diamond-faceted barrel ensures pen will not roll away if left uncapped on a desk.

Polished rose gold plated nib engraved with TWSBI logo and branding, available in a wide range of nib sizes.

141mm long closed, 130mm long open, 176mm long posted. 12.9mm max barrel diameter, grip section tapers down to 9.5mm. Weighs 28g.

Note: piston-filler pens cannot use cartridges.

Supplied gift-boxed.

Like all TWSBI fountain pens we stock, this pen can be entirely disassembled for the purposes of cleaning and servicing. Instructions and necessary tools are supplied with each pen. However, the disassembly feature is only there for experienced users and is not necessary for normal use. Disassembly is at your own risk!
