Have fun creating a galaxy of stars with our DIY sticker set. Glow-in-the-dark stickers shine beautifully at night for up to 6 hours. During the day the sticker absorbs sunlight for 30-60 minutes so please ensure it is placed in a well-lit environment. Can be used in a children's room, a baby room or as an indicator for wall switches.
