Turn your normal ceilings and walls into a magically starry night with these glow in the dark stars. After installing, simply expose objects to light for a full minute, turn out the lights, sit back, and watch them glow. When the glow fades, the objects can be recharged again and again for repeated use. Perfect for young space enthusiasts, or children who are anxious about the dark. Each pack contains 16 glow stars and double-sided adhesive tapes for sticking to flat, dry surfaces in bedrooms or playrooms. Make your own design wherever the adhesive will stick with these glow stars from 4M. Give your child the gift of science with toys that foster curiosity and encourage learning.
