This is an experiment kit used in the 5th-grade elementary school science curriculum, "Electricity and Electromagnets." Batteries are not included. I received this from the school, but my child isn't interested and won't use it, so I'm offering it for sale. Since there will be shipping costs, please refrain from price negotiations. I've checked the contents, and I believe everything is there, but the items in the photos are all that's included. Please understand if anything is missing. New ones don't seem to be readily available, so please take this opportunity to purchase it. To reduce shipping costs, I will take the contents out and fold the box to fit it into a Takkyubin Compact box. There are many items, so I won't be able to include cushioning material. Please understand. Please purchase only if you agree to these conditions.
