TWSBI ECO Clear fountain pen features an eye-catching design, with a clear barrel that shows off the pen's inner workings. It is the most economical one of the TWSBI fountain pens line up. 

As its body is made of a round clear plastic, it allows you to see the how the internal piston mechanism works, simple and elegant. It has a large piston filling ink capacity which is convenient for everyday use, and you could see how much ink left easily. TWSBI ECO comes at a great price for the filling mechanism, which normally much more expensive for fountain pen.

Writing is a pleasure with TWSBI fountain pen. The piston ink-filling mechanism is clean and smooth, and holds a considerable amount of ink. Its nib is smooth and ink flow is consistent, therefore very little pressure is required to write with this pen. 

It comes with a wrench and a vial of silicone grease for user self-serviceable maintenance.

A quick no brainer guide in choosing nib sizes in an overly complicated fountain pen world (by TWSBI):

If you write small, go with an EF;
For the normal writer, F is the most popular;
If you tend to lean on a bigger font, M will be perfect;
B is for statements!! Sign a check in B, write a header in B, do some coloring/shading in B; Stub nibs are italic in writing style (have a special card or invitation to write?)
