I tried to bring up the idea of "play well," which means "LEGO." Since this book is a paper brochure, I've added a lot of different materials to show you the differences in paper and how to use it. I even made a Lego box to keep the book and the idea of "play well." Although this was a paper promotion, my goal was not only to allow people to see the various uses of paper but also to preserve and experience different kinds of paper. When people look at a book, they look forward to something more exciting and varied. I chose the binding that matches the theme and made the small devices think one by one.
