A clean Eco with horse

The TWSBI Eco White Horse combines a clear demonstrator barrel with an illustration wrap depicting traditional Chinese good fortune and strength. It's the first decorated Eco and as much a collector's piece as a dependable writer. Uses the standard Eco nib and piston filling system, giving it high ink capacity and smooth feel.

What sets it apart

• First illustrated Eco model, inspired by Eastern artwork
• White cap for contrast against the clear barrel
• High capacity piston filling system for extended writing
• Reliable stainless steel nib across multiple sizes
  
• Transparent body to monitor ink level and flow
  

Feel in the hand

It’s a clean, light coloured Eco that feels more playful than most demonstrator pens. The artwork gives it personality, while the clear barrel lets your favourite ink become part of the design. This will be an enjoyable pen to use.

Who it’s for

• Anyone wanting their first quality fountain pen
• Everyday writers wanting generous ink capacity
• Collectors looking for a unique Eco special edition
• Journal writers and sketchers who enjoy ink pairing 

Not for

• Users who prefer darker or more understated tones
• Those who want cartridge or converter convenience
• Writers looking for a heavy, metal bodied pen
• Anyone who prefers fully opaque pens
  

Practical tips

• Staining inks are best cleaned promptly to avoid tinting the clear barrel over time.
