Review (4/5): Very cute, glittery and bright, colors change is not subtle
These are peel-off polishes so make sure you let them dry fully and top coat them with non-peel off topcoat thoroughly before soaking your hands in water to test the shift. They're also a bit more sheer than I would like, but nonetheless very cute.
Warm = light, cold = deep, bright.
Only real downside for me is that they come unlabeled. I'm fairly certain these are part of a larger collection of 12 colors, but I am not sure which ones in that collection are these supposed to be since some of the shades are very similar.
