I got this stunning Etude House polish a couple of months ago in a swap over at mua. Etude House polishes have the cutest bottle designs and I love them even more for that. I read somewhere that this might be a possible dupe of OPI's Unripped, but I think the shimmer in Edtude House's is more pronounced.
It only needs two coats to be opaque and I didn't had any issues with either the formula or the brush- the brush spreaded nicely and was easy to paint with. The color is a blackened teal with green and purple shimmer.
