Kodomo Challenge Programming Plus Tinkering Kit and Workbook, June to March. This was an option for Kodomo Challenge in 2022. It has been untouched since June and has been stored as is. The June workbook has some pages detached, but there is no writing. The July and later workbooks are completely unused. The kit box shows signs of use, but the contents are relatively clean. Please purchase if you understand that this is a used item stored at home.
