Well there are couple differences like price (10$ vs 32$) and there isn't a very visible shimmer in the Pro Golden and the Laguna has a sheen that isn't very visible either. Obviously there's packaging as well, Laguna comes with a weird sponge applicator (umm...yeah who uses that??) and Pro Golden comes with a very surprisingly good brush applicator. Both have mirrors. Now Nars offers 3 shades and so does Mark. But I could try all 3 Mark shades for less than the cost of just one Nars shade!!! That means I have more options for less cash...I'm all for it!
