TWSBI ECO (Clear)

The ECO has a simple design, but its filling mechanism is excellent, and a large amount of ink can be sucked in at once.
The transparent barrel and neck are beautiful with colored ink.
It is a perfect choice for customers who are new to fountain pens.


The nib is made of steel, and the writing feel is so excellent that it is hard to believe that it is made of steel.
The nibs come in five different widths: EF, F, M, B, and Stub 1.1.
