Opaque gold. Vinylux weekly nail polish is a system uniquely designed to work together. Exposure to natural light secures the prolight technology, creating an enduring, long-lasting polish. While ordinary polishes become brittle and deteriorate over time, vinylux dries naturally to a flawless finish and strengthens its resistance to chips over time. Week-long wear, self-adhering color coat. Self-adhering color coat means no base coat necessary. Durability increased with exposure to natural light.
