Perfect Quality.
Format: Hardcover, Format: Hardcover
Cloth bound cover with printed foil design on the front cover. The lettering color ; as well as the picture illustrations, are entirely printed in blue ink. There is a removable price sticker on the back of the book, which it is hard to remove without it leaving glue residue behind, therefore I myself left it as it was. The sprayed edges are also of blue metallic color. Very nice quality book I recommend buying it. My copy of the book had only a very tiny indentation on the edge of the top front cover but hardly anything to make a fuss about.
