The Uni-ball One Gel Pen is a premium writing instrument designed for those who seek precision, smooth ink flow, and a sophisticated writing experience.
Whether you're taking notes, journaling, or sketching, this pen delivers exceptional performance with its high-quality gel ink formula.
Featuring Uni-ball’s exclusive pigment-based gel ink, the Uni-ball One provides darker, richer, and more vibrant black ink compared to standard gel pens.
The ink sits on the paper surface instead of soaking in, preventing smudging and ensuring fast drying.
This makes it an excellent choice for students, professionals, and artists who require clean, precise writing with minimal feathering or bleed-through.
The sleek, modern body design enhances both style and functionality. A low center of gravity offers better balance, making long writing sessions more comfortable and reducing hand fatigue.
The matte-finish body provides a premium feel, while the sturdy clip-on cap ensures easy portability.
0.5mm Tip – Perfect for everyday writing, offering smooth ink flow and medium boldness.
0.38mm Tip – Ideal for fine details, precise note-taking, and intricate sketches.
