Mark's Academic Diaries
Hugely popular 15-month diaries from Japan
Mark's is an up-and-coming Japanese brand and their diaries are some of their best loved products. These unusual 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.
These diaries run from September until December the following year, so are both a calendar and academic diary.
