How hard is the ball point pen? At present, only Japan, Switzerland and China can make it! Of course, in the past, China's ballpoint pen heads were all imported.
It's no surprise that Switzerland can make a ballpoint pen head, because Switzerland's machinery manufacturing has always been very precise! World famous Swiss watch! Switzerland is a global leader in micro technology.
Let's analyze the structure of ballpoint pen.

"Manufacturing industry is a very basic element, indicating the development level of productivity in a country or region. A small ball point pen core tells us that technology is the first productivity. When gmtlight manufactures and assembles products, it will also encounter many problems. Some ideas and product innovations have to be abandoned because of technical problems. "
