400 Glow-in-the-dark Circles and Shapes Set | Vinyl Wall Decal | Phosphorescent Sticker This vinyl has am ambient, phosphorescent glow. This is a special material with a metal backing that was originally engineered for construction sites and fire exits. Once the lights are turned off our vinyl will glow up to an hour and recharge indefinitely! Use your imagination on how to install these stars.
