The main color of this mani is Picture Polish Cosmos, a vibrant royal blue with lots of scattered holo particles. Application was a dream, I used two medium coats. And as I wasn't changing my polish as often during my vacation, I can confirm a great wearing time: only after five days it had some little chips.
My ring finger shows the Norwegian flag (at least it's supposed to be the Norwegian flag, as I already mentioned before: me and freehand nailart = instant fail), using Essie Blanc (white), A England Perceval (red) and P2 So Cool! (blue).
As a finishing move, I added one coat of Essence Better Than Gel Nails Top Sealer.
