美国采购需求：适用于水域，m1镜

I'm reaching out to inquire about the availability of several units of your mirrors. I'm looking to purchase at least five pieces, and I would appreciate any information regarding the specifications, pricing, and lead times for these products. It would also be helpful to know if there are any bulk purchase discounts or special offers available. Additionally, I'm interested in understanding the delivery options you provide. If possible, please include details on the packaging and shipping methods you use, as well as any applicable delivery timelines. I'm eager to finalize this order soon, so a prompt response would be greatly appreciated. Looking forward to your reply!
