This is an electronic dictionary my son bought when he was in high school. He used it with a cover. It shows signs of use, but I think it still works. Includes stylus, operation confirmed. It will be initialized and shipped with the batteries removed. The following is a product description from the official website: For high school students aiming for further heights. Supports high-level English learning and high school studies for passing difficult universities. Includes a wide range of content, including English content that allows you to learn the four skills of reading, listening, writing, and speaking in a balanced way, as well as glossaries, reference books, and problem sets. Can be used from preparation and review to entrance exams.
