Nails Inc Miracle Buffer
This is absolutely stunning and so affordable. Don't expect it to tackle any massive ridges left by badly peeling nails (sort the peeling out instead!) but after only a few strokes, my nails were so shiny it was as though I'd applied clear polish. I use this before painting to give a smooth surface, and just to give my bare nails a touch of beautiful shine on their 'rest days'. I've already recommended it to my friends.
