Clear 'demonstrator' barrel reveals the filling mechanism, a built-in piston-filler with a very smooth action. The Eco-T version has a more triangular grip area, and matching triangular-shaped cap, for those who like the grip more tailored to the 'correct' way to hold a pen. If you hold your pen in a different way, the standard Eco model may suit you better. 

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 to the pen when not in use.

Faceted cap ensures pen will not roll away if left on a desk.

Polished steel nib engraved with TWSBI logo and branding, available in a wide range of nib sizes: extra-fine, fine, medium, broad and stub.

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!
