These came from the Moonlight Chase in Eldridge, IA a great race that starts after dark around the first or second week of July. This race runs through the neighborhoods and candles side by side light the road for the entire 4-mile race. This is one of our favorite races. These bracelets came in our packets, they are reflective and we wear them on our wrists after dark. You can see they roll up on their own and do not need fasteners or anything. We have found them very handy.
