GloPlay stickers draw their power from high-quality phosphorescent materials. These are stickers that will light up any dark space, adding tremendous vibrancy to even the most closed-off area – day or night. The glow-in-the-dark tech is so strong, you are going to love it. Because of the strong adhesive used for the stickers, they will stay on any surface you attach – while remaining easily removable when it's time for them to come down.
