哈萨克斯坦采购需求：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 for a high-quality A5 designed notebook that features a soft cover option, either in leather or silicone. Ideally, it should have around 350 pages, giving plenty of space for writing, sketching, or note-taking. It's important that the notebook offers double-sided printing to maximize usability, as I want to ensure users can make the most of each page. Additionally, I'm interested in the overall design of the notebook; it should be appealing and functional, making it suitable for both personal and professional use. Please provide information on your available options, including customization possibilities, pricing, and lead times for production and delivery. A sample of the material and printing quality would also be appreciated. Looking forward to hearing from you soon!
