阿根廷采购需求：益智玩具、蒙特梭利玩具、木制拼图、积木玩具、角色扮演游戏、婴儿玩具

I'm reaching out to inquire about your baby walkers. I'm particularly interested in understanding the production lead time and pricing based on different order quantities. Additionally, could you provide details on the international standards your products adhere to, including any relevant certifications? I noticed that you'll be exhibiting at the Canton Fair this May, and I'm excited to attend. It would be great to arrange a visit to your factory if possible, so I'd appreciate it if you could share your location details as well. Looking forward to your prompt response!
