The nail polish application is very easy. They come in gorgeous shades. You do need to put 3 coats on, because it is kinda of runny. I wore these for three days and on the third day it started chipping on my right hand (which is the one I use the most), so you may want to use extra top coat with this. The glitter duo is beautiful and only 2 coats need to apply the perfect glitter nail. I love them for two reasons; they're super cheap, and they make deciding what glitter to use with your base color is much more easier verses trying to pair up the hundreds of nail polish to get that perfect glitter nail look.
