Overall, 20 x 20 island displays two story display is likely to make the biggest impression, but other sizes are available. Look for those that offer ample viewing points, numerous display panels, and a layout that fits your product or service. Choose those that allow you to stand at the top and interact with your would-be customers. Select those that allow the visitor to virtually step inside the display to learn more. A variety of colors, styles and designs are available to fit just about any product or service available.
