The book is housed in a black box with turquoise sides with a fold-down flap held in place magnetically.

On the back of the book: "Book Binding Patent Pending - Kuch & Riedel" This is justified as the structure is unique in my experience being both a codex and an accordion. This is accomplished by small magnets holding each page to the page below in the codex form but which may be separated by separating the magnets and thus transforming it into an accordion fold.
