I'm looking to source notebooks or organizer planners specifically designed for promotional purposes. The preferred size is 21cm, and I'd like to explore options that feature a durable paper cover. It's essential that these products are suitable for branding opportunities, so please provide details on what customization options you offer, such as printing logos or other designs on the cover. Additionally, I would appreciate it if you could share the minimum order quantities, pricing tiers based on volume, and estimated production lead times. If you have any samples or images of similar products in your portfolio that fit this description, please include them with your response. I'm keen to understand how we can partner effectively for this project.
