This is a Confetti aka a bar glitter polish from Barry M, as you can see it has both aqua and lime bar glitters in a clear base. Sour Apple is from the Summer 2013 Confetti Collection. I chose to layer it over Key Lime because I thought they would go well together which they do, this one would go really well over a black too.
The polish went on well and the above photo shows one coat. I found I had to dab a little bit to get a good covering of the glitter but nothing too complicated. The finish was slightly bitty but nothing a topcoat can't smooth over. You could build this up to get a full coverage if you wanted to do so.
Sour Apple is similar (possible dupe) to Nails Inc's Brighton Feather polish.
