Explanation:
According to the excerpt from "The history of the biro", the development of the biro is narrated as Lewis Watermark secured the patent for the fountain pen in 1884. However, the problem with the ballpoint pens invented between 1888 and 1935 was that they couldn't write on ordinary paper ait tore through paper.
In June 1945, Milton Reynolds stumbled on the Biro pen in Argentina where he found out that the Biro brother's patent had expired when he sent some pens to Chicago.
The first biro factory began production on October 6, 1945.
