This naming does not mean a real murderer, but it means that the color fading and texture that have been worn for many years in the sense of "a real challenge" are reproduced so realistically that they can be mistaken for the real thing by modern processing technology and the enthusiasm of craftsmen. I put it on. No matter how many difficult problems are overcome, they will appear one after another, but it is also a fact that the degree of perfection is increasing year by year.
