This educational computer toy is recommended for children from the older preschool years through the early elementary grades! My child used this until around second grade. There are no major stains in visible areas, but there is some dirt on the underside of the mouse and the contact points, so please check the photos. Other than that, there may be some minor damage, but please understand that this is a used item. * Includes a separately sold adapter * Batteries are removed * No box or instruction manual The following is the manufacturer's product description: /////////////////////////// Programming education will be implemented nationwide in elementary schools starting in 2020. While many parents want their children to learn programming to develop logical thinking skills and for their future, they may feel anxious about not being able to provide sufficient guidance and support for this new type of education, as many teachers and parents have no experience with programming. "Mouse de Kisekae! Sumikko Gurashi PC" is a computer toy that not only has elements of play but also covers programming and major subjects, helping children with their studies.
