印度尼西亚采购需求：3D 标牌、3D 字母、通道字母、金属标牌、圣诞节标牌、工作场所标牌

I'm looking for more detailed information about your advertising light boards. Specifically, I'd like to know about their specifications, available sizes, and customization options. Also, what are the pricing tiers based on order quantities? Additionally, please share info on the lead times for production and shipping. Are there any warranty policies or after-sales support included with the purchase? It would be great to understand these aspects before making a decision. Thanks!
