澳大利亚采购需求：文件夹，塑料文件夹，卡套，TCG卡套，相册，婚礼相册

I'm interested in your ability to produce custom protective sleeves and folder pocket pages tailored to specific sizes. It's important for me to ensure that the materials used are PVC-free, so could you provide details on the types of materials you work with? Additionally, I'd like to know more about the customization options available—like color choices and size ranges. Is there a minimum order quantity for a small batch that I could use for a quality check? Looking forward to your insights!
