take for example
Hero 9 16 Boutique Pen
The smaller the number, the finer the representation.
I used to look at this number when I went to the painting and calligraphy institute to buy pens.
There are many kinds and models of pens. According to the composition of the nib, it can be divided into gold pen and iridium pen. The nib of the golden pen has high gold content, soft nib and small elasticity, and it is smooth and comfortable when writing. However, the gold pen is expensive, the nib is soft and difficult to master, so it is not suitable for beginners. Iridium pen has less gold content, hard and elastic pen tip, durability and low price, so it is a tool suitable for beginners to write.
When choosing a pen, it depends on whether the nib is smooth or not. You can check it by checking the pen, that is, dip the new pen in ink and write some strokes and * * * digital grooves on the paper. If the pen tip does not pull the paper and the water comes out evenly, then the pen tip is smooth and meets the use requirements. The nib is thick and thin, so you should use a pen with a slightly thick nib to practice writing. If you need to write with a pen with a smaller font, you can choose a pen with the word "extra fine" on the pen holder to write.
Pay attention to the maintenance of pens. When writing, pad some manuscript paper under the paper to enhance the elasticity of the pen tip and reduce friction. Don't write on hard objects such as metal to avoid damaging the nib. The pen should be cleaned once a month or so to keep the ink flowing. Pens should be cleaned and preserved if they are not used for a long time.
What needs to be mentioned here is that the elbow pen with the words "hard pen calligraphy" on the pen holder has the characteristics of great change in the thickness of writing strokes. When in use, the pen holder is pressed downwards, and the strokes are thick, so that slightly larger characters can be written; When the pen is vertical, the strokes will be fine, and you can write smaller words. This kind of pen is more expressive than ordinary pen, and is often used to write envelopes and other large fonts. But it is difficult to write with this pen. Beginners should not practice writing with it.
