Uni
The Uni-ball One is Japan's most talked-about gel pen. Its ink pigment sits closer to the surface than standard gel inks, producing a richer, darker black and more vivid colour saturation with every stroke. The white ink edition writes opaque white on dark paper, kraft paper, and over dried ink — an essential tool for journaling, illustration, and dark-background decoration. Writes smooth. Dries fast. Makes every page look better.
