FAQs

Is the Espresso colour very dark?
It is a mid-brown coffee tone, warm rather than black.

Does the bronze trim change over time?
It may develop subtle wear with use but generally retains its warm metallic tone well.

How is it different to the entry level Eco?
The colour way, and bronze finish on the nib and trim. The specifications are identical to other Eco models. The difference is purely visual.

Is it beginner-friendly?
Yes. It’s one of the most accessible piston filling fountain pens available.
