Made of a high quality polyester material, our UK Royal Standard flag measures 3' x 5' and includes vivid colors and an accurate design. The flag is screen-printed on a shiny polyester material and is finished with a double stitched hem. The flag features a white fabric header with two brass grommets on the 3' side for easy display. The flag is best used indoors but can withstand occasional outdoor use. The authentic design is based on information from official sources.
