Keep an Opal Mind (#439) is a shimmering, iridescent polish with a soft white base and delicate pink, orange, and blue-green shimmer that changes with light. With ProLight™ technology, it strengthens under natural light for up to 7 days of wear. Enriched with nourishing oils and keratin, it dries quickly and gives a glossy finish. Apply 2–3 coats and top with Vinylux Weekly Top Coat for best results.
