The gel pen uses ink with the new beadspack pigment developed by uni-ball. The absorption of the ink on paper is well controlled, making the colors more vivid and clear, and black color darker.
It is shown in a study in Japan that students can remember better using notes written with darker black ink by uni-ball ONE pen than notes written with other normal gel pen.
The pen body design is simple and minimalistic, giving a calm feeling to the user.
