I'm interested in your remote control cars and would love to get some pricing details, including bulk order discounts if available. Could you also provide me with information about your company, such as your manufacturing capacity, quality control processes, and any certifications you might have? Additionally, I'd like to know about the different models you offer. Specifically, any features that set them apart from competitors would be great. Looking forward to your prompt response so we can explore potential business opportunities together. Thanks!
