Thank you for viewing. This is the Kodomo Challenge 4th Grade "Sound and Light! Electrical Experiment Magical Checker." It can be used without the Challenge Tablet. Operation has been confirmed. You can review what you learned in 3rd grade about "things that conduct electricity and things that don't." We will ship immediately after confirming payment. If you're in a hurry, please consider purchasing this. We primarily use Yu-Yu Mercari Bin or regular mail, but we can also change to Raku-Raku Mercari Bin. If you prefer this, please let us know in the comments. We have many other items for sale, so please take a look! Type: Nature/Science Popular Keywords: Kodomo Challenge
