Night Sparkle is a black creme with gold microglitter. This is two coats no topcoat. I loved the formula on this one, it was so easy to work with.
Red Sparkle is a really dense glitter made up of micro and small red glitters. I used three coats and a coat of topcoat. I already have more red glitter nail polishes than I will ever use, but I just couldn't pass on this one.
Silver Star has medium holographic glitters in a dark grey glitter base. I also used three coats on this one, but another coat would have been better, since there were a few bald spots. This glitter combination also has a couple dupes in China Glaze Eye Candy and Sally Hansen Gem Crush.
Gold Sparkle is made up of gold and bronze microglitters. This was my favorite one out of all four polishes and it was the one I had initially skipped on. I used three coats and a coat of top coat.
I think Sephora really stepped up their game on this year's Hello Kitty nail polishes. The formula was a lot better on these than the ones from their permanent collection. The only thing is that these are a bit pricey at $10 per polish and there is no information about how much polish is in them, but it's definitely less than .5 oz. Still, the main reason why people buy these polishes is because of the insanely cute Hello Kitty shaped bottle and hardly care about the polish itself. ^_^
