“SKULLY” COLOR CHANGING NAIL POLISH “Skully” is a new black/purple color changing polish with glitters in neon green, neon purple and orange as well as purple skulls and tiny black hexes. The color is effected by the temperature of its surroundings ~ cold weather, sunlight, cold or warm water, or holding a hot or cold drink. When cold, this polish is black but changes to purple as it gets warm. Nail swatches are shown using 3 coats of polish with a clear topcoat. Thanks to Tiffany of polishandpaws.com for her awesome swatches! Using a top coat or base coat will not effect your color changing polish. Please do not leave your color changing polish bottle in the sun as it will effect its ability to change colors. For best application, shake polish before use. A good quality clear top coat such as Seche Vite is recommended for a smoothe and glossy finish. This listing is for a standard full-sized 15ml / .5oz bottle. Two stainless steel balls are included in every polish bottle.
