The effect is holographic,the price is reasonable (6€).
It stays long enough on the nails, mine chipped off after 5 days but I did used Seche Vite top coat.
It really is a beauty but maybe a bit too dull if there's no sun. I'm imagining myself on the beach with this one!
Applied 2 coats and Seche Vite Top coat.
Gorgeous isn't it? :)
