OPI is a great brand. I knew it was going to be awesome just by the brand name. This adds a much more fun twist to nail polish. After your base nail polish dries, you have to brush it on quickly because it shatters fast. If you don't get it on evenly fast then it looks clumpy. This product works and looks great. Naturally it's expensive and not exactly office-friendly. I love wearing bright neon colors as the base color and putting this on top. Brush it on thinly if you want more of a zebra-pattern. Brush on thicker if you want a blocky pattern. I recommend to brush on a clear top coat after this.
