Uni-ball One Gel Pen Refill

The Uni-ball One Gel Pen Refill is designed to keep your writing crisp and vibrant. Its pigment-based ink uses larger particles that sit on the surface of the page, producing richer dark tones and brighter colors that stand out clearly.

With a 0.38 mm or 0.5 mm conical tip, this refill delivers fine, controlled lines while drying quickly to resist smudges and bleed-through. Water and fade resistant qualities make it a dependable choice for everyday notes, journaling, or important documents. Compatible with Uni-ball One pens, it ensures a seamless extension of your writing tools.
