TWSBI Diamond Mini AL Fountain Pen. Transparent crystal-clear diamond-faceted barrel reveals the filling mechanism, a built-in piston-filler in aluminium with a very smooth action, whilst also allowing an uninterrupted view of the ink level and colour. Part transparent, part smoke-finish cap; aluminium grip section. Chromed metal 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 when not in use.
The end of the barrel is threaded to allow secure posting.
Polished steel nib engraved with TWSBI logo and branding, available in a wide range of nib sizes.
117mm long closed, 108mm long open, 140mm long posted. 12.4mm max barrel diameter, grip section tapers down to 9.8mm. Weighs 22g.
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!
