Suitable for school, office and everyday use, offering precision and convenience for both note-taking and drawing. The secret of the Uni-ball One lies in its unique "One Ink" pigment. Unlike conventional gel inks, which absorb into the paper fibres and can therefore make the colour duller, the Uni-ball One ink remains on the surface of the paper. The result is a significantly brighter and deeper tone that stands out on paper and is easy to read. The metal wire clip allows the gel pen to be easily attached to notebooks or pockets.
