美国采购需求：亚克力盒、亚克力展示盒、带盖亚克力盒、亚克力展示盒、透明亚克力盒、定制亚克力展示盒

I'm interested in sourcing custom mahjong tile sets, mats, and racks/pushers for a new boutique venture. Can you provide details on the minimum order quantities (MOQs) for each product? Additionally, I'd like to understand the average costs associated with different tile production methods, specifically for machine-engraved, hand-painted, and machine-engraved laser-painted tiles. Furthermore, are there any additional charges for creating unique tile designs or custom mat designs? I'd appreciate any info you can share regarding lead times, as well as the possibilities for customization to help differentiate my offerings in the market. Looking forward to your prompt response.
