In 1809, the United Kingdom issued the first batch of patent certificates for water storage pens, which marked the official birth of the fountain pen.
In 1829, the British James Bailey successfully developed a steel pen nib. It has been specially processed to be smooth and elastic. It writes smoothly and is very popular among people. However, this kind of pen must be dipped in ink to write, which is very troublesome.
By 1884, an employee named Waterman of an American insurance company invented a method of supplying ink through a capillary tube, which better solved the above problems. The tip of this pen can be removed and the ink can be filled with a small dropper.
The earliest pen that could absorb ink by itself appeared in the early 20th century, using a piston to absorb ink. When a leather bladder is used in a pen, an iron piece is inserted into a slit to squeeze the leather bladder to absorb ink. By 1952, the Schnocker pen, which used a tube to extend into the ink to absorb water, appeared. It was not until 1956 that the commonly used capillary pen was invented. There are also some art pens and so on.
Now, with ink bag pens, the old ink-absorbing pens are no longer needed. The ink bag pen does not need to absorb ink, just insert the special ink bag and you can use it.
