I honestly have no idea. The large pictures of the brushes look exactly like the ones I have. Having said that, I am not sure that M·A·C sells sets of full sized brushes like that. I've never seen them.
On the "deeply suspicious" side, the total retail value of the brushes alone at M·A·C in the USA is $209.50 - with a M·A·C pro discount this would be reduced to $125.70 which is still more than this seller is asking and that excludes the case. The economics simply don't add up.
I am also deeply suspicious of anything sold from China. There's no reason why highly realistic fakes can't be made, it's just that most fakers don't usually bother.
I will see if I can do some more research into this. It may take a while.
