"The Right Side Up" is a holographic thermal, which shifts from light blue to dark blue, all while shimmering with an intense linear holo. This nail polish comes in a 15 ml (.5 fl oz) bottle with a fan brush. A Note About Thermals: Thermals are a type of nail polish that shifts between multiple shades. The pigment works by shifting colors using heat, and over time, that pigment stops being as effective. Thermals have a recommended shelf life of 6 months before they stop transitioning and will become one of the colors permanently. To ensure the longest possible shelf life, store thermals in a cool dark place, and avoid placing the bottles near direct sunlight. To best extend the life of thermals, Apocalypse Polish makes thermals when you place your order, so please allow an additional week for processing (a total of 21 days until your order ships).
