新加坡采购需求：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 ordering customized stamp washi tape and would like to gather some details before proceeding. Could you please inform me if there's a minimum order quantity for this product? Additionally, I'm keen to know the pricing and lead time for shipping the order to Singapore. Furthermore, I'd appreciate guidance on the specific file types that you require for customization, both for the stamp washi tape and for the gold foil stamp washi tape. This will help ensure that I provide everything you need to facilitate the production process smoothly and efficiently. Looking forward to your detailed response!
