The quality of this powder is stunning - really finely milled of course, and you get practically perfect coverage and near full opacity from just one coat, though I always do two just to be safe. The depth of colour does come with a lack of strength, so you need to sandwich your black layers with a few coats of clear consciousness to prevent chipping or cracking, but because you don’t need many layers to achieve that deep pitch black you don’t have to worry about your nails getting too thick. It may initially look like the powder has stained your fingertips but don’t panic it comes off easy when you wash your hands afterwards.
