意大利采购需求：水袋背包、水袋包、水袋水袋、轻便跑步背包、水袋、运动包

I came across a couple of your backpacks on your website, and I'm really interested in making a purchase. Could you provide me with details on how to place an order for these items? Additionally, I'd like to know more about the payment options available. Also, please let me know about the shipping process to Italy. It would be great to have some estimates on shipping costs and delivery times. If there are any specific requirements for international shipping or customs duties, that info would be super helpful too. Looking forward to your response!
