Uni-ball One F Gel Pen | 0.5mm

All Pens are Black Ink

Enjoy vibrant, easy-to-read notes with the Uni-ball One gel pen. Its ink is specially formulated with large pigment particles that stay on the surface of the paper instead of getting absorbed into it. Since the ink isn't getting washed out by the paper, dark inks look darker, and bright inks look brighter. The ink is fast drying and bleed resistant too, so your notes will always be crisp and free of smudges.

Uni-ball One ink doesn't just look good—it may even help you be a better student. A study at Ritsumeikan University in Japan found that students who studied notes written with a black Uni-ball One pen were better able to recall the information than students reading notes written in ordinary black ink.

Compared to the original Uni-ball One, the Uni-ball One F features a wider barrel and a lower center of gravity, making it more comfortable to use for long writing sessions.

Features:

• Vibrant, pigment-based ink that is fast drying and bleed resistant.
• Comfortable plastic barrel with a low center of gravity.
• Wire clip that opens wide for attaching the pen to a notebook or textbook.
