The listing, Sun Reactive Color Changing Shoe Laces! Pink / White has ended.
This auction is for 1 pair of brand new shoe laces. These laces are so cool! They change color when they are in the sun! This pair is white normally, and then turns into a pink/hot pink when it hits sunlight. This pair is approx 37 inches long. I'm not sure the material they're made out of, nylon maybe? The second pic is a shot of them turning from pink back into white.
