Uni-ball Limited Edition ONE Gel Pen 0.5mm (Autumn Colors)
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.
