Review (2/5): Not Flat-backed
Stones and bigger pieces are not flat backed. The bigger pieces are round; you cannot use them on natural nails. The tiny shapes like the tiny moon and tiny starburst are nice and easy to use, but everything else is tricky. I wanted gems, but the gems are not flat so they come off super easily.
Description should describe that the stones are not flat and are in fact shaped like rocks.
Also, the color of the rocks scrape off so easily!! :(
