Z-Kai Programming Future Course with KOOV Sony KOOV Starter Kit + Advance Kit (※Includes Starter Kit + Expansion Parts Kit) and 2 years' worth of Z-Kai textbooks. Both are unused. Opened for content confirmation upon listing. I already have KOOV, and I bought this for my younger brother, but it never got used, so I'm putting it up for sale. I have confirmed that the main board is working. All 2 years' worth of textbooks and the Parent Support Guide are included. They are unused, and there are no writings in the textbooks. However, please understand that this is a used item. It will be shipped in a recycled cardboard box and plastic bag. Thank you very much.
