This is a CASIO electronic dictionary for high school students. It has only been used a few times, so it's an older model from a few years ago, but it's in very good condition and I think it can still be used. The batteries will be replaced with new ones before shipping. Only the case and the main unit are included; the instruction manual etc. are not included. https://www.casio.com/jp/exword/product.XD-SV4000/ You can go to the official product site from this link, for your reference (_ _*) Instant purchase OK^^ Please refrain from purchasing if you are nervous about home storage.
