Hey there :)
Along with the 3rd movie of the Twilight Saga, Essence released a Limited Edition with this theme. Needless to say, it was more difficult than other LE's from essence to get the things you've wanted. One thing that I didn't buy was the magenta/berry-colored polish called "Don't bite- Kiss me". But I bought the rest of the shades ^^
The formula on these were average- not too runny, not too thick. I didn't use a topcoat for the swatches.
My overall impression: These are nice shades. Most of them are opaque in two coats and they have a average dry- time. They might not be the "breathtaking, unique or I WANT THESE!"-shades and I can't see why these are inspired by Twilight, but I'm sure a lot of others (probably mostly Teenagers) will buy these, no matter what.
