e.l.f 28 is a polish that I found at Target. From what I understand it is a Target exclusive and so is the rest of the Fall "Python" Collection. ("28" is on the bottom of the bottle and is the only indication of the polish name.)
28 is a black polish with a shimmer that goes from pink to blue to purple depending on the light. The pictures do not do it justice...especially since you can only see the blue shimmer. I found it to have an even consistency, however the brush was rather small.
