Gel pen is convenient, but the writing quality is poor. To tell the truth, buying a good one is very expensive.
Ballpoint pen, commonly known as oil pen, is characterized by being very slippery, but it is very slippery. The most important thing is that it is very cheap, 1 yuan. Generally, it is written in words with a thickness of 0.7 and the words are not fine, just to be fast! ! Write a receipt or something to deal with running errands.
Pen and brush are soft calligraphy, and pen is hard calligraphy. Brush can write lines with different thickness according to the position, direction and strength of holding the pen. However, the line thickness of the pen will not change much because of the nib, and it is two different ways to hold the pen.
Therefore, writing with a brush is not necessarily good. The same font and font are written with pens and brushes, mainly because the lines create different contents. A brush has more room for change on paper, while a pen is smaller.
This is the difference, I hope I can help the landlord! Typing so many words is really tiring. I hope the landlord can accept it. Thank you ~)
