Release your inner goth with this Black Dragon thermal nail polish, which is black when cold and transitions into a gorgeous blue grey when warm. Our unique thermal nail polish transforms based on temperature and can be layered for deeper colors, and it can be used with various application techniques like water marbling to create artwork on your nails. Featuring a touch of sparkle, this premium polish is suitable for natural or acrylic nails and dries matte. Our salon quality nail polish can be finished with a clear top coat for that luxurious, 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 Black Dragon bluish grey thermal nail polish is cruelty-free and 10-free.
