However, he had to refill it all the time. The ink also did not dry easily, and it sometimes made a mess on the paper. Biro wanted a better pen. His brother, George, helped him develop a special ink. The ink dried easily. Then they developed a new type of pen.
There was a tiny ball at the tip of the pen. The ball rolled ink onto paper as it move. They called it the “ballpoint” pen.
The ballpoint pen was a great success. Everyone loved it. Now millions of people use it all over the world every day.
