Sing Along 4-book set, picture books, Disney English System. I listened to the basic songs, and I only read the picture book "I". I flipped through the pages once or twice, so "I" has a slight crease. Book 2 has a small scratch on the spine, and the spine is slightly discolored, but the inside is otherwise relatively clean. Since I've graduated, this is a great deal for those who want to try it out! This is a copyable product, so returns are not accepted. Thank you for your understanding.
