南非豪登省约翰内斯堡采购需求：一次性手套，一次性 PVC 手套，乙烯基手套

I'm looking to place an order for a total of 50,000 boxes of blue vinyl gloves in size large. It's important that these are powder-free, as we have specific requirements for our projects. Could you please provide me with details on the pricing, lead time, and any quantity discounts available? Additionally, I'd appreciate information on your quality assurance measures and any certifications the gloves may have. Looking forward to your prompt response!
