A pen is a pen-like writing tool that mainly uses metal as a pen. It is filled with ink (mostly black or blue) through a hollow pen tube, and is written by gravity and capillary action, and then written by a duck-billed pen. Different from light and heavy, it can be said to be a writing instrument for Western calligraphy. Most of the pen's ink can be refilled, usually using a vial such as eye drops or a straw to fill the ink. The earliest history of water-filled pens dates back to the 10th century, and the earliest water-filled pens were used until the 18th century. The development process was slow, but it was not until the early 19th century that a pen that stabilized the accelerated flow was invented during the production process. Only three key inventions have made the pen a widely popular writing instrument. These inventions are: tinned gold pen tips, hard rubber and free-flowing inks.
The first pen that used the three key inventions above was built around the 1850s. But it was not until the 1880s that mass production began. France's Waterman (Widwin) and Wirt were the main producers at the time. Waterman later swallowed Wirt. Become a big company with a pen as a professional. Now with Parker and Montblanc, it is also called the world's three famous pens.
