I've had this for a long time. I'm selling it to declutter. It's old, so I think it's hard to find. *Regarding the condition, there are some places where the gaps between pages are starting to tear. Please refer to the photos and only purchase if you understand. Please refrain from purchasing if you are a perfectionist or overly concerned about details. Please only purchase if you understand that this is a used item. Immediate purchase without comment is possible ○ Feel free to ask questions. #Handbook of Chemical Substances #Chemical Handbook #Reference Book #Handbook #Ministry of Health, Labour and Welfare #Chemistry #Dictionary #Chemical Society of Japan #Computer #IT #Natural Science and Technology #Education #Chemistry #Handbook #Dictionary #Chemical Handbook #Decluttering #Hygiene Management #Ministry of Education, Culture, Sports, Science and Technology #Hygiene Manager #Labor Research Institute #Safety Management Manual #Safety and Health Manager #Industrial Safety and Health Act #An'ei (Safety and Health) #Book #Industry/General #Industrial Safety Consultant #Occupational Health Consultant
