A GOOD, USED BOOK
Used very good (sách cũ - rất tốt) is the highest condition of used books. Books are readable with no defect, no tear or wet. Like a friend lending you her old books.
Some readers might prefer used books to new ones because of the history it carries. Oftentimes, we bumped into a side note, an author signature, a photo used as bookmarks, a silly drawing from a student in class. Or just the awesome vanilla smell of a used book we know you'd like.
