The Christian and American flags, 3' wide X 2' high, are made of nylon. Each flag comes with an iron stand and a two-piece aluminum pole. The 73" tall, gold-colored stands are weighted in the bottom to make them tip-proof. Because of their size and weight, children can easily carry the flags down the church aisles during VBS. Although the flags are made of nylon they are majorly for inside use. It is possible you could use them outside for a short period of time, but they probably would tend to tear or fade.
