The Urban Graffiti Photochromic range is one of our most adventurous ranges we've ever released, the colours reacts dramatically to daylight and UV rays causing them to change to a darker colour. These polishes are great for someone who gets easily bored with their nail colour or someone who just wants to inject a bit of fun into their designs. This colour changing gel polish is a way to wow your friends and clients when they see it change from one colour to another in the blink of an eye!
