A Parrot Polish favorite named for our owner’s wife, Sonja’s Folly is a triple threat thermal nail polish that changes color based on hot and cold temperatures. A deep purple black when cool, our unique polish transitions to violet and then to hot pink as it warms up. Featuring chrome dust for a hint of shimmer, this premium polish is suitable for natural or acrylic nails and can be layered for deeper, more opaque colors. Our salon quality nail polish dries to a matte finish, but add a clear top coat for a sophisticated, high-gloss shine. Our line of thermal polishes are easy to apply, and dry quickly with a smooth finish. As with all of our Parrot Polish products, non-toxic Sonja’s Folly purple thermal nail polish is cruelty-free and 10-free.
