A Ballpoint Pen Is A Pen That Uses Tiny Rotating Beads
Jul 25, 2018

The ballpoint pen is a writing instrument that uses dry thick ink and relies on the freely rotating steel ball on the pen head to be transferred to the paper. It has the advantages of simple structure, convenient carrying, writing lubrication, and suitable for rewriting.

A ballpoint pen is a pen that uses tiny rotating beads made of brass, steel or tungsten carbide that releases ink onto the paper as it is being written. The ballpoint pen is very different from its predecessors, the reed pen, the feather pen, the metal pen tip and the fountain pen.

A ballpoint pen is a writing instrument that uses ink to rotate the ink onto the paper. After the Second World War, ballpoint pens were introduced to China. The savvy businessman made a big "negative pen" advertisement, and opened the market by the Yuwei of the atomic bomb that exploded in Japan. In fact, the "ball-point pen" has nothing to do with the atom, but the pronunciation is similar. Ballpoint pens quickly became popular in the world. Japan alone consumes 400 million ballpoint pens a year. The reason why the ballpoint pen can write is because the steel ball in the pen can bring the quick-drying ink out and transfer it to the paper when it rolls. It is said that the dry ink in the Japanese ballpoint pen is enough to write 20,000 words. However, after writing more than one word, the gap between the steel ball and the steel tube will gradually become larger, so that the ink will leak out of the gap, often staining the clothes, etc., which is very unpleasant.
