I'm looking for information on a 3D mobile billboard box. Specifically, I need details about available options, including sizes, materials used, and any customization features you offer. It's important for me to understand how these boxes can enhance visibility and capture attention in various environments. Please provide any technical specifications, and if possible, include examples of previous projects or installations that demonstrate their effectiveness. Additionally, I'm interested in bulk pricing options and lead times for manufacturing and delivery. If you have any recommendations on the best configurations or designs for outdoor advertising, I'd love to hear your insights. Lastly, if you have product manuals or brochures, please send them along as they will help in making an informed decision. Looking forward to your prompt response!
