The makeup brushes are all wrong (wrong animal hair/synthetic, wrong placement, wrong brush shape, and/or the metal part of that holds the hair is wrong). As to makeup I generally do not buy makeup from China, especially cheap or counterfeit makeup, as you really cannot trust what they put in the ingredients. You only have 1 face and 1 pair of eyes. If you don't want to pay MAC prices for their products in your country then try cheaper stuff at the drugstore or wait for deals from other brands like UD, Stila, MUFE, Sephora, etc. There are hits and misses with every brand at every price level and I would rather be safe than sorry. (I would say wait for a MAC sale but as far as I know MAC has only ever gone on sale once during the recession in the US where they gave out 10 or 15% discounts to people. Otherwise the only discount I ever see is free 2-day or overnight shipping).
I'm not trying to say that all of the cheap/counterfeit makeup from China is unsafe but this is the same country where a company was able to sell rice mixed with fake plastic rice to their own consumers to save some money. Unless the product is being overseen by a major overseas company for quality control, I would not risk it. (i.e., not makeup but Apple and Samsung have their phones and phone parts made in China and those factories are under strict and severe quality control)
