印度采购需求：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 looking to purchase a variety of envelopes for our upcoming projects. We need both standard sizes and some custom ones as well. Quality is key, so please provide options that have a sturdy feel and clear printing ability. Additionally, it would be great if you could send me your pricing details, available colors, and any bulk order discounts. I'm interested in establishing a reliable partnership, so timely delivery is essential. Looking forward to your prompt response!
