#Shinken Zemi #Supplement #ElectronicDictionary #PerfectStudy #JuniorHigh1stGrade #EnglishWords This is the "Perfect Study" supplement from the Shinken Zemi junior high school course materials (from a few years ago). I had difficulty balancing it with my塾 (cram school), so I stored it away with almost no use. Operation has been confirmed. I will send it with the AA batteries installed (I don't know how long the batteries will last). Also, the earphones are unopened and unused. By the way, there is no instruction manual. It seems you can understand how to use it by touching the screen. This is a used item that has been in someone else's hands, so please refrain from purchasing if you are concerned about minor details. Shipping will be via Mercari's anonymous shipping service. I would be happy if you would consider it. Thank you very much.
