Everyone likes to write in different ways, so the writing surface formed on the pen is different. That pen is comfortable to use because it is suitable for your writing angle after your running-in. Generally speaking, the lubrication degree of a pen has little to do with the tongue, but personally, the ink output of different pens has an influence on the smoothness of the pen. A pen with a large amount of ink is naturally smooth. If you think the pen is not slippery, you can improve it by grinding particles with polishing strips and drawing eight characters on the glass.

The quality of the pen tip can be tested by the following simple methods: when buying a pen, write casually with a new pen tip on ordinary paper naturally and continuously, and if it feels smooth, you don't have to scrape the paper; At the same time, we should also feel that the pen tip should be elastic (this needs constant practice); And redemption. Pay attention to the length and thickness of the pen to match your hand shape. This hand type refers to the difference between men and women, the difference between fat and thin, and so on. , subject to self-comfort. Plus ink, these are related to the fluency of the pen.
