Kleancolor has a half dozen of these holo glitter polishes in different colours; I decided to layer the pink and the orange over 2 coats of Milani Retro, which is a pastel coral creme with subtle shimmer (and a nice formula!).
These are holo glitters, not smooth holo particles, so they do dry rough. They also don’t dry all that quickly, but don’t take as long as the Kleancolor layering glitters which can sometimes be really bad! Shown are two coats of each glitter, with top coat. On their own, they may need 3 coats for opacity; I’m not sure.
The pink and orange are both pastels; they appear darker and more pink/coral here because of the coral polish underneath.
I didn’t really care for the pink all that much on my skintone, but I really like the orange and plan to try it on its own as well as over other bases. Also looking forward to trying Holo Yellow!
