When using a ballpoint pen, have you ever had the experience of falling off the ball and leaking ink; The writing is intermittent... These conditions have a lot to do with the ball socket body stuck on the pen tip. Because the opening thickness of the ball socket is less than 0.1mm, it should not only fit the ball properly, but also ensure smooth writing without ink leakage. The interior of the pen tip is even more complicated. There are five grooves guiding the ink inside. The processing accuracy must reach the order of one thousandth of a millimeter, which is thinner than a hair.

At present, there are many private customized pen products on the online shopping platform. Merchants can engrave idioms and names on the pen according to the needs of buyers.
