the history of the pen

The pen is a kind of pen-like writing tool with metal as the pen body. It contains ink (mostly black or blue) through a hollow pen tube, and then writes through a duckbill pen through gravity and capillary action. It can be said that it is a writing tool of western calligraphy. Most pens can be refilled with ink. Generally, small bottles or straws such as eye drops are used to come to refill kit.

The earliest historical record of water storage pens can be traced back to the 1th century, and this earliest water storage pen was used until the 18th century.
