I am selling a collection of items I don't have much memory of playing with. My two children subscribed to Challenge Touch and Challenge, so the "Quiz King Review" has cards from both of them mixed together, and I am selling two of the same item. All items have been tested and confirmed to be working. Please check the official website for instructions before purchasing. Please refrain from purchasing if you are overly concerned about minor details. I will offer a 100 yen discount if you choose Eco-Mercari delivery.
