These banner stands are incredibly popular in places like Korea for their portability and ease of use.
X-Stand Banners are lightweight and cost-effective ways of displaying your graphic. As the banners are hooked onto the stand using grommets on all four corners of the banner, this means you can easily replace the graphic by yourself. Just order a reprint, and install it yourself.
This means this is a great way to advertise any promotions you might have or showcase products.
