This 16.5' shark flag is intended for display Indoors on any concrete or other hard surfaces using the chrome X-base. The banner design is customized to your graphic artwork and is printed on a polyester mesh by the process of dye sublimation. Our inks heavily saturate the material for a deep high-quality print. A layer of blackout material is included in the center to increase the visibility of the artwork. Black flag trim is sewn on the edge of the graphic (pole-side), leaving a pocket for the pole insertion. A set of grommets are installed on the bottom of the trim in which the short bungee cord (included) can loop through and snugly attach the graphic to the base.
