All our Deluxe Sharkfin Banners are supplied with chrome plated ground spikes and durable nylon carry bag with handle and zip. Optional extras & Printing: For use indoors or on hard surfaces we have two freestanding base options, namely: Indoor Cross Base (single flag system) and Cluster Base (four flag fountain system). Optional Water filled bags can be purchased and placed over these bases to make it more stable in higher wind conditions. All our custom branded Sharkfin Flags are dye sublimated in full colour digital and are colourfast ie, fully washable and dry clean safe. Our printed flags are available in single or double sided versions, single sided being the industry standard and the most cost effective and popular. Single or Double Sided: Single sided flags are printed on Banner Mesh Fabric which has tiny holes in to let wind pass through resulting in a much longer life span compared to regular printed flags. Double sided flags are printed on double sided Ultra Sheen fabric with block out in between. Each side can have a different design if need be. Please note, double sided flags are heavier and do not ‘wave’ in the wind as freely as single sided ones.
