美国采购需求：和纸胶带、计划贴纸、牛皮便签、日记卡、翻领别针、金属书签

We're currently exploring the possibility of expanding our product line to include rub-on transfers for our crafting enthusiasts. Our existing range features custom decoupage napkins, tissue paper, and rice paper designs, and our customers are eager for us to provide more options. Could you provide us with the available size options for the rub-on transfers? Additionally, we're looking to offer a mix of designs. Some will be simple black on transparent backgrounds, while others we envision in vibrant full color. It would be great to know if you can accommodate these design preferences and any details on minimum order quantities or lead times. Looking forward to your insights!
