OPI Nail Lacquer in Scorpio Seduction is a cobalt blue nail polish with a pearl finish, part of OPI's Big Zodiac Energy collection. The pearl finish gives the deep blue a soft glimmer rather than the flat, matte-like look of a crème polish.
Two thin coats over a base coat build full opacity, and a top coat helps protect both the color and the pearl shine from chipping. Saturated shades like this one can stain bare nails if applied without a base coat first.
