This electronic dictionary can be used for studying not only English proficiency exams like Eiken and TOEIC, and English conversation, but also Japanese language and social studies. It also includes other convenient search tools and features. The main unit has no noticeable scratches or stains, and there are no malfunctions. A case is also included, but it has some fraying, so we recommend replacing it. New batteries have been installed, so you can use it immediately upon arrival. Instant purchase is welcome, thank you.
