加拿大采购需求：和纸胶带、计划贴纸、牛皮便签、日记卡、翻领别针、金属书签

I came across your company through a friend's recommendation, and I'm impressed by your stamp washi tape services. I'm interested in placing an order and would like to know a few details. Could you let me know if you can produce 10 designs per roll? Also, what's your minimum order quantity for each design, and do you offer any discounts for bulk purchases? Additionally, I'm curious about the available sizes, acceptable file types for custom designs, and whether you print in CMYK or other color options. Thanks!
