“2024 Edition Thorough Guide to Mechanical Maintenance [Mechanical Systems/Practical Skills]” Japan Management Association Management Center Price: ¥2900 I purchased this book for the January 2026 exam and successfully passed using it. In my subjective opinion, there's no need to buy the latest, more expensive version. There are no markings. I used a book cover, so there's almost no dirt or damage. Please do not purchase if you cannot understand the following after reading it to the end. I will not trade with those whose transaction rating is 2 or less, or those who do not greet me after purchase, and I will cancel the purchase even if made (to prevent recent Mercari troubles such as item swapping). I will lower the price at my own pace. I will ignore and delete negotiations for significant price reductions. Please check the condition in the images and only purchase if you understand that this is a used item, not new. Please comment if you have any questions. I will use recycled materials for packaging. Shipping included (seller pays) I do not create dedicated pages, so I recommend purchasing as soon as possible. Recently, I have had many transactions with people who lack common sense. To avoid unpleasant experiences for both parties, please only purchase if you meet the following criteria. If you cannot follow these, I will give a negative rating. Those who can make pleasant transactions Those who can offer standard greetings Those who can communicate frequently Those who can communicate in Japanese Those who understand used items and are not overly sensitive Those who can pay immediately if using convenience store payment Those who can check the contents and provide an evaluation immediately after receiving the item
