卡塔尔采购需求：小型断线钳、钢丝钳、管钳、水泵钳、管子钳、航空剪

I'm reaching out to inquire about pricing and availability for several products we're interested in. We're looking at ordering a total of 500 units for each of three specific models, plus a larger quantity of another model amounting to 5000 units. Could you please provide the details on your pricing tiers, lead times, and any minimum order requirements? Additionally, if there are variations or options available for these models, I'd love to hear about them. Looking forward to your prompt response!
