The first and most intuitive thing is to look at the length. Wolf hairs are not very long, within 5 centimeters. Ninety percent of the hairs exceeding 5 centimeters are fake (there are a very small number of hairs about 6 centimeters in length, which are extremely expensive!), or they are a mixture of several types of hair. Made from both sides.
Secondly, look at the price. Generally, the cost price of small Kailang cents is more than 10 yuan, and those sold in the market usually cost more than 30 yuan each. If the price is lower than this, it is very likely that it is mixed with other wool. Of course, some people like this kind of wool or artificial hair, which is another matter.
Smell the smell. When you get the wolf hair pen, first put it under your nose and smell it. Some of the pure wolf hair pens that have not been processed will have a dog-like smell. Fake langhao pens tend to have the smell of chemical dyes due to craftsmanship problems, or have the smell of sheep because they are mixed with wool.
Look at the color. The pen head of pure wolf hair is lighter in color and has natural luster. The color from the root of the hair to the tip is from light to dark. However, there is one production method that is really difficult to distinguish, that is, the outside is made of real wolf hair, and the inside is usually made of dyed wool, dyed bristle, artificial hair and other materials. This kind of pen can only rely on the integrity of the seller and the discernment of the buyer (it can only be identified after opening the pen).
Feel! The real wolf hair feels like touching a very healthy pet cat with bright and smooth fur that is bathed frequently. It feels very comfortable to the touch, while the fake wolf hair will feel rough to the touch. ?
Finally, when writing, the real langhao pen will have even force without dispersion, and the strength is soft, and the whole pen will feel integrated, giving a feeling of playing with a soft sword; the fake langhao pen will have a small tip, The belly of the pen is big, and it feels like two independent parts. The writing of heavy and light is completely different. The tip of the pen is weak and weak, while the belly of the pen is frizzy and difficult to control at all.
