Please check my profile, just in case. It's the Obunsha Scramble English Grammar and Usage 4th Edition. It says a CD is included, but it wasn't included when I received it from a classmate. I ended up not using it. When you open the cover, there's some paper stuck to it and it's dirty (see the second picture), but it looks like it can be removed without any problems, so if you're concerned, please cut it off yourself. I'm sorry it's dirty. The Purin-kun mascot is not included.
