I'm interested in sourcing a specific product with a pan silver finish. I'm looking for one that has a thick or robust design, as durability is essential for our needs. Could you provide details about the available options, including the materials used, dimensions, weight, and any other relevant specifications? It would also be helpful to know about the manufacturing process and any quality control measures you have in place. Additionally, please share your pricing structure, including bulk order discounts, lead times for production, and shipping costs. I'm aiming to evaluate multiple suppliers, so any information regarding minimum order quantities or payment terms would also be appreciated. Looking forward to your prompt response with all the necessary details to make an informed decision.
