This is a set of three books: the 9th edition of the Paramedic Standard Textbook (Volumes 1 and 2) and the Emergency Medical Treatment Procedures manual. They haven't been used in class, but there is some writing in them with markers and pencils. They show signs of use, but are in relatively good condition. If anyone is interested, please let me know. The original price for the three books was 23,400 yen.
