What are the characteristics of the dark tip and bright tip of a pen?

According to the structure, pens can be divided into: dark tip, bright tip, semi-bright tip, pocket tip and calligraphy tip.

2) Sharp: large amount of water, good writing feeling and strong elasticity;

3) Half-tip: It has the advantages of even entry of dark spots into water and good writing feel of sharp spots;

4) nib (victory nib): it is not easy to maintain, and this nib is basically not used;

5) Calligraphy tip (artistic pen, artistic tip): It consumes a lot of ink, and the writing effect is close to that of a brush, so it is not suitable for daily use.
