Possibly the worst product I've ever tried. It was extremely messy - the powder went everywhere but on my nails. The application was uneven at best, and not at all visible at worst. I would never, ever buy this again, and it's too bad. I expect a lot more from Dior.
This is a great new product; a clear base coat for nails with a loose powder that when applied over the base bonds to it to give a sheer, long lasting shimmery affect. It's very easy to use, and instead of chipping or peeling away it just gets worn away gradually and fades. I find this is much easier to use than regular nail polish and when it fades too much I just reapply. There are 5 colors, mauve, rose, white, beige and gold. They are all lovely. Like all Dior products it's expensive but should last forever. You can find this at any Dior counter or at Sephora.com.
