ECO Matcha * TWSBI

 The TWSBI ECO fountain pen features a transparent body and a piston-filling system that can hold nearly 2 ml of ink. A well-sealing cap ensures that the pen writes with a smooth ink line at every start. The steel nib is available in different line widths from EF to Stub and writes effortlessly.

 Each ECO comes with a wrench and silicone grease to dismantle and clean the pen easily. It is not necessary every time, but it is helpful if you have used some characterful ink.

 Changing the nib on the TWSBI ECO requires some attention. The feed is quite sensitive and there are no separate nibs for sale for the ECO/T. You can search the web for information before you start this job.

 The ECO and ECO T are the most popular fountain pens. The only difference is in the shape of the finger grip and the filling button. In the Eco, they are hexagonal, and in the ECO-T, they are triangular.
