I'm reaching out to inquire about your products, specifically focusing on quality and pricing. We're exploring options for a potential order and would like to understand more about what you offer. It'd be great to receive a detailed catalog or product list, including any MOQ, lead times, and customization possibilities. Additionally, if you could provide any certifications or quality assurance details, that would be super helpful. We're keen on establishing a long-term partnership, so any information on your manufacturing processes and capacity would also be appreciated. Looking forward to your prompt response!
