uni-ball One Gel Ink Pen 0.5mm Pink

The newly developed ”Uni-ball One” ink uses a new pigment that minimizes the penetration of coloring materials into paper fibers, unlike general gel ink. As a result, the color material on the paper surface develops the original color, black is darker, and the color is more vivid. The oval-shaped ”Open wire clip” has a stylish design and is a movable clip that can be easily inserted notebooks.
