uni uni-ball One 3 Gel Ink Multi Pen - 0.38mm (2 colors)

Uni Mitsubishi uni-ball one 3 — The Cozy, Twist-Select 3-Color Pen (0.38mm) ☕✨

Need to pack light for a cafe journaling session but refuse to compromise on your fine-line color coding? The highly anticipated uni-ball one 3 has officially arrived at Techo Treats! This marks the very first time Mitsubishi Pencil has brought their iconic, ultra-dark gel ink into a seamless, rotating 3-color multi-pen layout (featuring Black, Red, and Blue).

Dressed in the soothing, earthy tones of Sugar Brown and Grass Green, this 0.38mm extra-fine model is designed specifically for paper lovers who adore clean, tiny handwriting inside crowded monthly grids and delicate Hobonichi or Traveler's inserts.

✨ Why It’s Absolute Stationery Therapy

• The Famous Ultra-Dark Ink: Powered by uni's proprietary pigment technology that sits cleanly on top of the paper fibers instead of soaking in. Your black ink stays incredibly deep, and your accent colors stay punchy and hyper-visible—even at a tiny 0.38mm line width.

• The Innovative "Stabilizer Mechanism": No more scratchy, hollow multi-pen clicks. Uni integrated a heavy metal tip clutch inside the nose cone, shifting the center of gravity downward. This eliminates any tip wobble and provides a remarkably steady, fluid writing experience.

• The Perfect Short-and-Sweet Profile: Standard multi-pens are often awkwardly long and top-heavy. The uni-ball one 3 is intentionally designed with a slightly shorter, comfortably contoured barrel (129.1mm) that balances beautifully in your hand and slips neatly into standard binder pen loops.

🎨 Available Barrel Variations

• Sugar Brown: A warm, comforting caramel-tinted neutral that pairs beautifully with vintage cream planner inserts.

• Grass Green: A soft, organic, nature-inspired green that brings a breath of fresh air to your desktop setup.
