The Twsbi Eco is a piston filler fountain pen, meaning it has the filing mechanism built into the body of the pen - simply dip the nib into a bottle of ink and turn the screw on the base of the pen and the ink chamber will fill up with ink.
It can hold up to 2ml of ink making it a perfect pen for anyone who writes a lot and doesn't want to be worrying about frequent refilling.
With nib sized from extra-fine to 1.1mm stub there is a Twsbi to suit every style of writing. If you're looking for smooth writing sensation we would recommend the medium nib or broader.
It uses a rubber o-ring on the cap thread to ensure 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.
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!
