It is as thin and hard as paper-based sandpaper, and it is coated with a blue-gray substance. Writing with a brush dipped in water can show the equivalent of black text. After a while, when the water is dry, the handwriting will be gone, and you can practice it again and again.
The big one is less than ten yuan, and the small one may be one or two yuan. Because I haven't bought it, I often buy rice paper (I am an old man, I just write and draw every day, and I have to buy several thousand yuan of rice paper a year). The boss gave me this kind of paper, so I asked my little granddaughter to practice, without asking the price. At that time, I said I gave him money, but she said it was not worth much money.
This kind of "practice paper" feels similar to fringed paper and is more suitable. Xiao Zhang's granddaughter practiced. I wonder how many times she can write it over and over again. After writing in the water, it is still very flat, unlike ordinary paper wrinkles.
