Z-Kai, LEGO Education Spike Prime. LEGO Education SPIKE Prime (45678 Version 29) Used by a child for about a year. All parts are included. Z-Kai children's workbook and parent guide are all included. There are writings in the children's workbook, but the explanation part is readable, so I think you can learn without any problems. I think this is a very good product for children who are interested in LEGO. Please understand that this is a used item and purchase it. ☆ Confirmed the number of all included parts. Many spare parts are also available. ☆ Confirmed the operation of hubs, sensors, and other modules. iPad Bluetooth connection confirmed. Remarks The Z-Kai program has ended. I work full-time on weekdays, so it may take some time to reply to inquiries and ship the item. No smoking, no pets. We do not accept any cancellations or claims after purchase. Please purchase only if you understand.
