Ballpoint pens
Balancing Smoothness and Reliability
Japanese-made ballpoint pens are highly regarded and popular worldwide for their performance. The ball’s surface at the tip of the pen requires two contradictory qualities: being smooth for easy ink flow and a firm grip on paper for reliable writing. AKS balls achieve both of these qualities at a high level.
