Dear Sir, I am going to start a business on aluminum nuts based on the attached map and given data. The initial quantity would be 300, 000 pcs. Please kindly bear in mind that there should not be any leakage from these nuts because they are going to be applied in natural gas and home gas and air-conditioning supplies. Please give us your bottom-most quotation, commercial and payment terms, and possibly pictures. Looking forward to your prompt reply! Sincerely
