# TWSBI Eco Fountain Pen - Indigo Blue with Bronze

## An Eco with a slightly dressier feel

The TWSBI Eco Indigo Blue with Bronze takes the standard Eco demonstrator and gives it a more composed finish. The deep blue resin sits somewhere between navy and ink blue, while the bronze trim softens the overall look and stops it feeling cold. Still the same reliable piston filler underneath, just with a colour way that feels more settled and intentional.

## What sets it apart

-   Deep indigo blue paired with warm bronze trim
-   Reliable piston filler with high ink capacity
-   Smooth steel nib with free tuning before dispatch
-   Crystal clear barrel lets you track ink level and movement
-   A darker demonstrator that still feels approachable

### Feel in the hand

The Indigo Blue with Bronze feels calm and dependable. The darker blue gives it a more serious tone, while the bronze trim adds a little warmth and softness around the edges.

### Who it’s for

-   Writers who prefer darker, more refined colour palettes
-   Everyday users who want reliability and capacity
-   People who like subtle contrast and warm metal finishes
-   Blue ink users looking for easy ink pairing
-   Anyone wanting a demonstrator that feels a bit more grown up

### Not for

-   Users who prefer bright or highly saturated colours
-   Those who want cartridge or converter convenience
-   Writers looking for a heavy, metal bodied pen
-   Anyone who prefers fully opaque pens

### Practical tips

-   Try brown or sepia inks if you want to bring out more warmth from the bronze trim. Blue-blacks make it feel cleaner and more formal.
