e) In case the ball does not rotate on paper 1

• A Ballpoint pen transfers ink from pen to paper by rotating ball on paper. For this reason, the ball may slip on the paper without rotating on the paper, such as coated paper, copied paper, or paper drafted with a pencil or sharp draft, and ink may not come out.
• When writing on thin paper or when the writing pressure is weak, the area of contact between the ball and the paper is small, so the ball may not rotate on paper and ink may not come out.

＊Pressurized Ball-Point Pen “POWER TANK” has adopted a spike ball to the pen tip of the ball of the unevenness of the micro (0.7 / 1.0mm only), is even more by pressurizing the ink, it is easy to transfer ink is also a smooth paper.
