The stiff upper edge keeps the flag at attention until a breeze comes along, causing it to swivel 360 degrees around the pole. Motion flags are double stitch sewn on 100% nylon. Each motion flag is finished with heavy bleached header and 3 brass grommets on the vertical side. Motion flags read correctly on one side and reverse on opposite side. Motion flags are 3 1/2' x 5 1/2'. Bracket for Motion Flag is sold separately as L1990.
