The Ballpoint Pen
Ages have gone and many things have improved as well as the writing machine which was once a dipped quill pen and now has become a ballpoint pen.

The ballpoint pen is a writing instrument which features a tip that is automatically replenished with ink. This tip is consisted of a formed metal ball placed in a socket. The socket
is responsible for holding the ball which fits loosely enough to roll freely but not loose enough to fall in our fall out that will allow the ink to leak.

The ink is stored in a cartridge. This ink cartridge is connected to the tip. The ball becomes coated with ink as it rolls inside and carries ink out. While the pen is moved along a writing surface, the ball produces ink which leaves the paper a mark.

People might think of a pen as a simple material or object for a simple work. Yet unknowingly, it is more than a valuable thing existing as a crucial invention.
