尼泊尔采购需求：促销品、促销礼品、广告礼品、挂绳、赠品、硅胶腕带

I'm interested in your selection of eco-friendly bags and would like to know more about the pricing options available. Could you provide details on the price range for different sizes and materials? Additionally, I'd appreciate it if you could include any volume discounts or promotional offers you might have, as I'm exploring options for bulk purchasing. Also, I'd like to understand your lead times for production and delivery. It's important for me to know the minimum order quantities required, as well as the customization options available. Knowing these details will help me assess how your products can fit into our upcoming projects. Looking forward to your detailed response!
