A baillpoint pen is an instrument to modern write. A baillpoint pen had a intern camera filled with a viscous ink. The manufacturing are economic and reliable.
The ballpoint pen went through several failures in the project initially. It was even argued that a project by Galileo Galilei, it was that of a ballpoint pen.
Today is a essential object to write.
I choose the pen because for me is very importante in more varied work.
