This is a DVD set of three years' worth of Kodomo Challenge Hopp and Jump, for children born in 2016. Hopp includes issues from May onwards. Jump originally ran until December, and issues from January onwards were for elementary school preparation, with DVDs for Challenge 1st Grader. These are also included. All DVDs were stored in separate cases, so the paper cases are all in good condition. All discs have minor scratches, but there are no playback issues. As the habit of watching DVDs has decreased, some Jump and Challenge 1st Grader DVDs have been watched only once, and some Challenge 1st Grader DVDs are unwatched. There are a total of 21 discs. How about a set for three years of kindergarten?
