This 4 x 6 ft. American flag is made of 2-ply, spun open weave polyester fabric that lets wind pass through which reduces stress on the flag. Features densely brilliant white embroidered stars, hand sewn alternating red and white stripes with four rows of fray-resistant lock stitching on the fly end. Finished with a polyester header and #2 brass grommets. These flags are ideal for long-term, daily commercial use - nothing beats the performance of polyester. Made in the USA.
