If your looking to buy only 1 side you can leave me a note at checkout what pattern and what side you want. https://youtu.be/l0-PIN7U4KE Each flag is made from a 2.5 mil oracal 651 vinyl Oracal 651 is a performance grade vinyl well suited for indoor and outdoor applications. It was originally designed for fleet vehicle graphics making it a perfect choice for cars. The solvent based permanent adhesive makes it a great choice for wet area applications such as boats or other outdoor places. For best results I would suggest a wet install At a temperature of over 45 degrees and use a hair dryer to help set the adhesive.
