The brush uses bamboo as the pole and animal hair as the nib-this is probably the origin of the word "pen". Animal hair has moderate hardness and strong water absorption. Used in calligraphy and painting, fluent and free. There is a lot of charm between Teton and Teton. No wonder it has been at the top of "Four Treasures of the Study"? Think about it, too. Whether it is Wang Xizhi's Weeds or Qi Baishi's Ink Shrimp, how can it be separated? However, this kind of artistic pen is only popular in China and some eastern countries because of its high requirements on pen holding posture and pen lifting speed.

Pencil:

During this period, there was an episode in the pen family, that is, the appearance of pencils. This method has been used since the ancients found that carbon rods can be used to scribble words and graphite can also be used to scribble. However, whether it is wood carbon rod or graphite, it is very easy to get dirty if you hold it directly in your hand. Smart humans put a coat (mostly cork) on carbon rods and graphite rods. Problem solved. Therefore, a small member has been added to the pen family. Its biggest advantage is that the handwriting is easy to change, and there is no trace of handwriting when the eraser is wiped. It is a good partner for beginners and a good friend for painters.

Pen:

Pen, the "junior" of the pen family, appeared in Europe. Pen, also known as fountain pen, is a portable pen made according to the principle of air pressure. The pen container is an empty rubber cylinder. Squeeze it to let the air out. After release, the air volume inside increases and the pressure decreases. The pressure difference between inside and outside is large, so that ink is sucked into the pen holder. When writing, the pressed ink flows out with the pen tip under the action of gravity. In this way, you don't have to dip in ink all the time, which greatly saves time. Moreover, writing is very smooth and convenient, and the handwriting is symmetrical and beautiful, so the pen quickly replaced the feather pen and became popular all over the world. It's "shine on you is better than blue"!

Pens are the favorite of pen owners. Practical, beautiful, smooth and convenient, with many varieties and brands, it is beyond the reach of other pens.

My little pen is very cute. Its body is like a thick willow, and it is like a pillar in the ant world. Its hat is golden, with a golden braid on it, shining golden like a sword. Open the hat and see its mouth like that of a kingfisher. Its body can be twisted, and unscrewed is the abdominal armor and stomach. I feed it every week to make it full, so that the pen can help me with my work.

Ballpoint pen:

Later, westerners invented a ballpoint pen which is more convenient for writing. Its main part is a round bead core, which consists of a hollow plastic tube similar to a quill pen and a pen with movable metal beads (hence the name ballpoint pen). Because the plastic stick is made of oily writing material, the trouble of ink leakage of the pen is avoided and the writing time is longer (generally, a bead core can be used for 2 to 4 months). This kind of ballpoint pen has become the "darling" of pen owners because it is lighter, more convenient and more economical, and is favored by people of all ages, especially young people.
