Children in primary schools have just started to practice writing, or are just about to write well. It is recommended to use ordinary student pens. It is not recommended to be too expensive, such as special writing or gold plating.
The reason is that the child's hand is still in the development stage, and the posture of holding the pen should be corrected from time to time. Overweight pens are not conducive to the development of hand bones. And if you don't understand, it's more troublesome.
Older junior high school students specialize in practicing calligraphy for a period of time. Pens commonly used by students, such as Picasso 9 16, Baile 78G or 88G (with a hard nib and fast writing speed) and Yongsheng 589, are all good pen types. It is suitable for practicing calligraphy and doing homework.
For working adults, if they just practice hard-pen calligraphy every day, there is a calligraphy pen recommended by Wang Zhe of Ziyunzhuang, which Taobao can find, with high cost performance and tens of dollars. If you need to write it out, Hero 100, Syaraku 050 1, Platinum 3776 (this is expensive) depends on your personal preference.
The reason is that the prices of the above three models range from 100 yuan to 1000 yuan, and they can be used to practice writing, sign documents and write materials every day, which is very convenient.
