I bought this book for the paper quality and to be inserted into an A5 traveller's notebook styled journalling/planner system. I just haven't better quality paper and a notebook that lays flat as well. And I have extensively searched for such a notebook including very popular traveller's notebook companies around the internet. It's very good for junk journalling. The paper can hold quite a bit.
I love that there is no bulky hardcover and I'm not super afraid to get it messed up. It's versatile.
