A blue hardcover reference book containing information specializing in mechanical engineering. - Title: 2000 Machinery Mate - Language: Japanese - Contents: Information on mechanical engineering - Color: Blue - Format: Hardcover It's convenient because it condenses specialized information. Even with changing times, the basics remain the same, so I've used it as a reference book. It is a used book, but I believe it has no severe stains or folds.
