澳大利亚采购需求：运动裤、慢跑裤、慢跑服、瑜伽裤、健身裤、紧身裤

I'm planning to launch a gym clothing line and came across your products, especially interested in the men's tank tops. Could you provide me with details about the materials used, sizing options, and any customization services you might offer? Additionally, I'd love to know about your pricing structure and minimum order quantities. Any info on lead times for production and shipping would be really helpful as I look to kick off this venture. Thanks!
