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.
