A pen that manages to juggle three colours without ever appearing flusteredquite the social grace. The Mitsubishi Uni-ball One Tri-Colour Gel Ink Pen brings together black, red, and blue in a single, thoughtfully designed barrel, making it a quietly indispensable companion for notes, edits, and the occasional emphatic underline.

Its party trick lies in the rotating selector: a simple twist aligns the colour ring and extends your chosen ink with a pleasingly smooth motion. No frantic clicking, no guessworkjust a gentle, intuitive turn. The slightly thicker barrel sits comfortably in your hand, while a low centre of gravity and internal stabiliser keep your writing steady and composed, even during longer sessions.

And then theres the ink. Uni-ball Ones gel formula delivers crisp, richly pigmented lines that dry quickly and resist smudgingso your thoughts remain as clear on paper as they are in your mind.

What Makes It Work So Well

• Three colours, one elegant motion: The rotating selector lets you switch between black, red, and blue with effortless precisionno clicking chaos.
• Crisp ink that behaves: Uni-ball One gel ink produces bold, clean lines that dry quickly, so you never smear your carefully written notes.
• Comfort you can rely on: A slightly thicker barrel and low centre of gravity ensure stable, fatigue-free writing throughout the day.
