I am selling this because the exam is over. I will also include the "Mock Exam" and "Kore Dake!! 50+". However, the mock exam is detached from the main book. A red sheet is also included. There is no writing in the book. Also, since it is used, there are some creases and stains. Thank you. #Class 4 Fire Service Officer #Class 4 Hazardous Materials #U-Can #Dangerous Materials Handler
