This is a reference book for the Class 4 Hazardous Materials Handler (乙4) exam. I passed the exam thanks to this book, so I'm offering it to those who will be taking the exam in the future. No writing, no folds, and it comes with the separate "2 Mock Exams," "Point Collection," and a red sheet. Since it's a used item, there may be some minor stains. ■Product Name■ U-Can's Class 4 Hazardous Materials Handler Quick Study Lesson, 4th Edition [Separate Point Collection, Practice Mock Exams, Red Sheet Included] (U-Can's Qualification Exam Series) ■Publisher■ U-CAN ■Author■ U-Can Hazardous Materials Handler Exam Research Group ■Published■ 2019/07/10 ■Price■ ¥1,480 + tax There are no smokers or pets in the storage home.
