Designed for outdoor use, these beautiful long-wearing 48 Star flags are crafted from the highest quality 200-denier nylon. Sewn stripes with appliqued stars make for a high quality flag. Attaching to a pole is easy with the canvas header and brass grommets. The hem on the fly end of the flag features 4 lock stitched rows to help prevent premature fraying. The authentic designs are based on information from official sources.
