Not worth the price... [SEP] $30 for these is too much. Half of the powders come with significantly less in the pots than others, not cool. The silver powder works the best in terms of mirror effect, the rest are more holographic. The colors are not nearly as bright or defined as those pictured, many of the colors are very similar. They're okay, but I wouldn't spend this much again. I'm going to try out some of the cheaper powders from. The biggest reason I bought this was because it was prime and I didn't want to wait a month.
