I like this polish because it’s actually an assortment of glitters with different sizes and colors. Some rainbow glitters are only a couple different colors, but this only is an actual rainbow. To get full opacity of glitter on your nails, paint a single coat and let it dry. Take a disposable makeup sponge (the triangle ones) and paint a bit of the glitter polish on a small section of the sponge. The apply the glitter on the sponge to your polished nails. The polish base will absorb into the sponge, leaving the glitter on top. Repeat the steps as many times as you like to build up the glitter on your nails.
