uni uni-ball One 3 Gel Ink Multi Pen - 0.5mm (2 colors)

Uni Mitsubishi uni-ball one 3 — The Modern, Twist-Select 3-Color Pen (0.5mm) 👔🧱

For the thinkers, the fast note-takers, and the planners who want their words to jump off the page with bold, contrast-heavy clarity—welcome to the uni-ball one 3 in a smooth 0.5mm medium tip.

This elegant tool breaks away from the bulky, corporate aesthetic of old-school multi-pens, replacing it with a clean, continuous-line twist mechanism that switches between Black, Red, and Blue ink with a whisper-quiet rotation. Available in the deeply sophisticated shades of Shirt Blue and Brick Red, it brings a sharp, architectural edge to your daily creative desk space.

✨ Why It’s Absolute Stationery Therapy

• Bold, Contrast-Heavy Flow: The 0.5mm tip size maximizes the flow of uni's celebrated pigment-rich ink. It delivers a rich, matte line that stands out brilliantly on both bright white grids and soft cream sketchbooks, drying quickly to prevent left-handed smudging.

• Zero Tip-Wobble Writing: Multi-pens are notorious for rattling while you write. Thanks to the built-in brass "Stabilizer" nose-cone clutch, the internal ink cartridges are held firmly in place, lowering the center of gravity so the pen practically glides across the page by itself.

• Sleek Wire Clip Design: Features uni’s signature open-wire pocket clip that opens wide to snap safely onto heavy canvas binder covers, thicker notebook journals, or shirt pockets without losing its tension over time.

🎨 Available Barrel Variations

• Shirt Blue: A crisp, minimalist slate-blue that evokes the cool, refreshing energy of a freshly pressed cotton shirt.

• Brick Red: A deep, muted, terracotta-tinted crimson that adds a gorgeous touch of mid-century modern style to your pen pouch.
