As the polyurethane is not looks good, but the quality is no problem.
P U not looks good is our factory weakness, it is the problem of mold of polyurethane, because mold after many years using, it makes P U surface is not smooth. But replace the mold is very very high cost.So we can not solve this problem in a short time.
Even if the P U is not looks good, the quality is very well.
The useful life of our P U is much longer.
