英国采购需求：和纸胶带、计划贴纸、牛皮便签、日记卡、翻领别针、金属书签

I am interested in sourcing self-adhesive note pads. Specifically, I'm looking for pads that contain 50 sheets each, with dimensions of 3 inches by 3 inches. It's important that the adhesive is strong enough to hold securely on various surfaces, while also allowing for easy removal without leaving residue behind. Could you please provide me with detailed information about the available options? I would like to know about minimum order quantities, pricing tiers based on volume, potential lead times for production and delivery, and any customization options that may be available. If you have samples or catalogs, I would love to review those as well to ensure we find the best fit for our needs. Thank you!
