{"type":"firestarter.listing","listing":{"id":"lst_rzEE2zAa","product_name":"Robin's Egg | DEATH VALLEY NAILS","category":"nail polish","description":"by DEATH VALLEY NAILS\n\nLight grey = shade / Blue = sunshineThis matte photochromatic polish transitions from light grey to blue and has a variety of black, brown, and gold glitters and flakies to look like a speckled robin's egg. This polish is activated only by sunshine/UV light. \nCare: photochromatic polish will actively transition for up to two years if kept in a dark and cool environment. We suggest using a base coat and 2-3 coats of polish followed by a top coat.\n\nDeath Valley Nails creates nail polishes by hand in small batches using innovative ingredients. Their products are non-toxic, cruelty-free, and made without phthalates and parabens.
