Jade is a Limited Edition color.
The TWSBI ECO is a beautiful, yet practical and affordable, piston-filler fountain pen. The crystal clear body and grip section allows for an unobstructed view of the ink level in the barrel, which holds a little over 1.5ml of ink.
The opaque hexagonal cap is threaded and posts fairly high on the barrel, without interfering with the piston knob, and features a silver clip. An inner cap also provides a seal when the pen is stored for longer periods of time.
The Eco is refilled by turning the piston knob counter-clockwise until the piston is at the front of the barrel, and then submerging the nib section in ink and turning it again clockwise to draw the ink into the barrel. There are no cartridges or converters!
TWSBI also includes in the box a tool to disassemble the pen and silicone grease for regular maintenance.
Note: Ink is not included with this pen.
