This is a set of three books: the 9th edition of the Paramedic Standard Textbook (Parts 1 and 2) and the Emergency Medical Treatment Procedures. While these books were not used in class, they do have markings from highlighters and pencils. They show signs of use, but are in relatively good condition. If anyone is interested, please consider purchasing them. The original retail price for the three books was 23,400 yen.
