How discover boll pen?

Answer 1

The ballpoint pen was invented by Laszlo Biro, a Hungarian-Argentinian journalist, in the 1930s. Frustrated with fountain pens that smudged and required constant refilling, Biro designed a pen that used a tiny ball bearing to dispense ink as it moved across the page. This innovation allowed for a smoother writing experience and greater convenience, leading to the widespread adoption of the ballpoint pen after it gained popularity during World War II. Today, it remains one of the most commonly used writing instruments worldwide.
