According to what you said, these costs and prices are above 1000, depending on what kind of tree species are used, but I think it should be radial pine or New Zealand pine (these two kinds are mostly used in furniture and imported materials). The steel mattress of 1.8 is in the range of 1, 000-2000/ set, and the small parts depend on the sample size. It is really reasonable for the merchant to give you 1 0,000. Can only say that it is more profitable.
