新加坡采购需求：圣诞铁盒、咖啡铁盒、糖果铁盒、茶叶铁盒、饼干铁盒、香草和香料铁盒

I'm looking for custom metal/tin packaging for Panettone at my restaurant. We need a circular tin, food-safe, with dimensions of 24.7cm diameter x 19cm height. The order will be for 300 pieces plus 2 samples, with a customizable design (we'll provide one). Could you let me know the unit cost, delivery charges, and lead time? We're okay with using existing molds if they match our size requirements. Looking to finalize this soon, so your prompt response would be appreciated!
