The ink composition has been reviewed to improve the smoothness while maintaining the vividness of the ink color and the ability to draw ultra-fine lines without bleeding. Uses a dark, non-bleeding water-based pigment ink. It also has excellent water resistance and light resistance. A new design with no noticeable joint between the grip and the shaft. The simple, smooth and flowing shape is attractive. In addition, the entire toe shaft has a rubber grip that is easy to grip.
