TWSBI Eco Fountain Pen Serpentine with Bronze
Currently unavailable, more stock due February 2026.
TWSBI Eco fountain pen with a clear 'demonstrator' barrel revealing the filling mechanism - a built-in piston-filler with a very smooth action. Features marbled green caps with a bronze trim and pocket clip, and the TWSBI logo nicely finishes the top of the pen's cap. The rubber o-ring on the 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 bronze-coloured steel nib engraved with the TWSBI logo and branding, available in a wide range of nib sizes.
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!
Orders placed before 3pm Monday to Friday will normally be sent out the same day.
