Six months ago I bought the whole Rainbow Honey Equestria collection. The polish I was most excited for was 20% cooler. It only took me till now to pull it out and wear it! That's the problem when you buy too much at once which I seem to do all the time. I never get around to wearing everything I wanted to wear. It was actually thanks to my Husband that I wore this because I pulled out two glitters and had him choose since I couldn't make up my mind. I guess there is a good use for Husbands after all.... hahahah j/k. I had Zoya Blu out on my desk so on it went. 20% cooler is a multicolored glitter suspended in what looks like a blue base. However the blue is more of a shimmer that once on the nail isn't as noticeable. I do like it over the light blue however If I were to ever wear this one again I'd put it over a black. That way the Blue Shimmer would really be seen. This would look good over any color!
Overall I love the instant Glitter Rainbow this puts on your nails!! Glad I finally pulled out the bottle!
