As soon as I read about the new Crackle effect nailpolish I had to get hold of it! I put the crackle on top of two coats Metallic Silver or White nailpolish, finish it off with a shiny top coat and it looks stunning. I've found that if you put a bit of heat on it like blowing it a bit with your hairdryer the cracks are bigger. It also lasts for ages on one's nails.
