These are a fine formula. They seem to be a lot of dupes of other polishes, so if the polish you want to dupe is over $5, you can buy these. Some of the polishes are quite pretty!
Hard Candy Envy is a black jelly with dark bluish green shimmer. Screams Zoya Suvi with way less shimmer. This is less $$ but also less pretty.
Hard Candy Hot Pants. When I saw this I said "Oh, hey! Nubar!" But it's cheaper and just as nice as their jelly glitters, so hey why not?
Hard Candy Mr. Wrong. Now this is a fairly close dupe of the incredible Sally Arabian Night I posted not too long ago, and while the base color isn't quite the same (I think Sally's is prettier) there is far more golden shimmer here, this is a STUNNER I would suggest everyone buy!!
There's another I have but I haven't swatched it yet. Stay tuned.
