The best reference book for the Fire and Disaster Prevention Equipment Technician exam. - Title: Fire and Disaster Prevention Equipment Technician Class 3 - Author: Fire and Disaster Prevention Equipment Technician Examination Research Group - Publisher: Denkishoin - ISBN: 9784868321053 - Price: 2500 yen Thank you for viewing. I read it with a cover, so the book itself is in good condition, I think. Regarding the contents, there are many places with writing and markings. I found them helpful when I reviewed the material, so I will pass them on as is, but since they are all in pencil or friction pen, you should be able to erase them to make them less noticeable.
