CDs for learning civil law, all 5 discs, plus booklet. Regular price: 7,260 yen (tax included) I bought these, but I only used them once. Since they are the listening type, they are suitable for busy people. Regarding the "co-ownership" topic, although there have been some recent revisions to civil law, there is no problem with understanding the key points. Stored at home, so please refrain from purchasing if you are overly concerned about condition.
