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

I'm interested in understanding the purchasing options for your products. Could you please let me know the minimum quantity of rolls that I can order? Additionally, it would be great if you could provide some information on pricing tiers based on different order volumes. This will help me in planning my procurement strategy more effectively. Thanks!
