I'm reaching out to inquire about your OEM and ODM pricing structures for large custom orders. We're interested in understanding your pricing tiers, minimum order quantities, and any volume discounts you may offer. Additionally, it would be helpful to know if you have any lead time estimates for manufacturing these custom products, as this will assist us in planning our inventory. Furthermore, could you provide insights into the types of materials and production capabilities you have? We're keen on ensuring our specifications align with your manufacturing processes. Lastly, if possible, please include any relevant documentation or samples that showcase your previous work in similar projects. Looking forward to your detailed response!
