Once I swatched this in a store I knew that I needed to have it! Upon application I don't think you can see a super strong rainbow effect but I do love how this looks on the skin. I think its nice that you can create your own color mixtures depending where you apply your brush. I also like that this product is very versatile and can be used as an eye shadow palette as well. I'm in love with the texture and the fact that there aren't any chunky glitters.
