OPI Nail Lacquer in Sky Blue's the Limit is a turquoise-blue shimmer polish, part of OPI's Trip to the Brite Side collection within OPI's standard Nail Lacquer line.
The shimmer finish means the colour carries fine silver-toned sparkle rather than a flat, solid tone; it goes on semi-sheer in a single coat and builds to full, opaque coverage over two coats.
Like the rest of OPI's Nail Lacquer line, it is formulated without formaldehyde, formaldehyde resin, toluene, camphor, or dibutyl phthalate (DBP), and is designed for use with OPI's own base coat and top coat as part of a 3-step system.
