As a detachable sheet, the drawings are small format, often very small, but it's still doable. Being able to detach the leaves makes it possible to carry around, it's like a lined pad of paper, you can take off a page. The quality of the drawings is good but the style varies, that does not give the impression of having been made by the same author, the type of cover design is quite different from the content, and the word Japan actually encompasses everything that is Asian, unfortunately.
