The oil of the ballpoint pen is too slippery, making it difficult to grasp the strength of the pen, and the characters written are ugly, and it is easy to make the fingers tired under the situation of heavy workload. As a former doctor, I would say that almost all the medical records you see online are written with ballpoint pens. So doctors hate using ballpoint pens. In the water pen, the ink is water-soluble and can naturally penetrate into the paper, like a pen, without too much effort.
Ballpoint pen beads fall off easily. I don’t know how many beads I lost when I was reading. On some special occasions, falling beads will cause various inconveniences. Sometimes it is even necessary to hold a magnifying glass all over the floor to find beads.
The only advantage of ballpoint pens over water pens is probably that oily ink can write on some special surfaces that cannot seep into water. For example, when we were children, we used ballpoint pens to scribble on the table, or even make cheat sheets or something. . . But now there are markers, which can be used much wider than ballpoint pens.
