I'm interested in purchasing some pieces from your factory and would like to get more details on how to proceed with the order. Could you provide information on the minimum order quantities, pricing per unit, and any available customization options? Additionally, I'd like to know about the lead times for production and shipping, as well as your payment terms. It would also be helpful to understand your return policy in case any issues arise with the order. If you have a product catalog or samples, please share those as well. I'm looking forward to your response so we can move forward with this potential purchase. Thanks!
