Could you provide more detailed information about your product range, including specifications, pricing, and lead times? Additionally, if you have any promotional materials or catalogs, that would be helpful for our assessment. We're particularly interested in understanding the quality assurance measures you have in place and any customization options available. Are there minimum order quantities we should be aware of? Also, it would be great to hear about your company's capacity to meet varying demand levels, as we aim to build a long-term partnership. Looking forward to your response and excited about the possibilities of working together!
