These unusual Japanese diaries incorporate a zipped bag in which the weekly diary fits. You don't have to unzip the bag to open the diary but you can store items in the bag such as a pen, phone, calculator or notes.
The clear front allows the stored items to be seen and displayed, creating your own cover design. The diary is a week to view over two pages with vertical columns for each day. Information inside includes subway maps for London and other major cities, holidays for 28 countries including UK, and much more.
