We love these battery operated color changing lights for all sorts of play. You may have seen glow in the dark egg hunts with mini glow sticks, but those are one time use. These lights can be used again and again. We have used them for months (sometimes leaving them on for hours 😅) and we haven’t had to replace a battery yet. Plus, they change colors so it adds to the experience. LTKKids LTKFamily LTKSeasonal
