The purple hair in the brush is made of the hair on the back of a rabbit's neck. Because the hair on the rabbit's back is purple-black, it is called purple hair, and the brush made of purple hair is called purple brush or purple cream hair. Zihao has a shiny surface, hard front glume and thick and straight hair shaft. Wet it and knead it into a flat shape. Look carefully, the front glume is slender, dark brown and transparent.

Generally speaking, the length of Zihao pen is less than 4 cm, and it can only be used as a small pen. In addition to the black needle hair, the mountain rabbit also has a side screaming flower tip. The quality of this kind of side pointed hair is not as good as that of black pointed hair, and the price is not as good as that of purple pen. Except the authentic Hu Pen, most of the other producing areas are dyed black wool or black wool, and its quality and cost are incomparable with the authentic Zihao Pen.

The strength of rabbits in the north and south mountains is also different, and some of them are made in the north and south. North millisoft, also known as Huai rabbit hair, means Huaibei, Anhui, but the northeast is better.
