The brush was one of the widest brushes I've ever used. It made application a breeze. They've done a lot of upgrading with this brand since I bought 119A. The Park Ave bottle says "quick dry", and it really is. Each coat dried in way less than a minute and subsequent coats went on like butter.
I really like this polish. It's a bit darker on the nail than in the bottle, but it's still a really pretty color. It seems to have a little bit of a purple undertone going on, which is interesting. I don't know how unique this color is (probably not very) but I'd still recommend it. I'd be anxious to try the other colors in this line, since I love the formula so much, but the other colors I saw in the display left a lot to be desired.
