Development History
In 1895, a commercial non-writing ballpoint pen was also sold on the British market. However, it failed to become popular due to its narrow use. In 1916, someone in Germany also designed and produced a new type of ballpoint pen. Its structure was relatively close to that of a ballpoint pen, but its performance was poor and it failed to attract widespread attention.
In 1936, Biro in Hungary was responsible for text proofreading in a news printing factory. When correcting the proofs with a pen, wetting and blurring often occurred. For this reason, Biro began to wonder whether he could trial-produce an other type of printing press. writing instrument instead of a pen. After a period of experimentation, he filled a steel round tube with quick-drying ink and installed a steel ball on one end as a pen tip.
Then he conducted writing experiments on various writing materials and found that they could leave indelible marks and the ink in the pen tube was not easy to spill. The experiment was successful. In 1940, he improved his invention, applied for a patent on July 10, 1943, and started putting it on the market in 1945.
