Denim blue from Snowcrystals spirng collection is a jeans blue metallic polish that almost looks a bit duochrome in the bottle because it has a pink microglitter.
I really like this color, it has a softnes over it but still look cool. You don't see much of the pink micro glitter on the nail though.
The formula is a bit thin, if you take too much polish on the brush it can become messy. To get it opaque I need three layers.
