LEGO Education SPIKE Essential Set + Manual Set for Z-Kai Programming Course Selling because my child no longer plays with it. Overall, there are no noticeable stains, but please understand that it has been played with by a child. The manuals (both Z-Kai workbook and parent guide, issues 1-12) are included. There are no writings in the manuals, but there are some slight sun-fading marks. Before listing, I confirmed the contents, and only one white crystal (circled in red in photo 8) is missing. I have confirmed that all other included items are present. The module parts have been tested and are working, and there are spare parts. #LEGO #Lego #ProgrammingRobot #Programming #EducationalMaterials #LEGOEducation #LegoEducation #MINDSTORMS #Mindstorms #LegoSpike #EV3 #NXT #mindstormsev3 #STEAMEducation #STEAMEducation #Robotics #ScienceProject #SummerVacation #WinterVacation #ChristmasPresent #NewYearMoney #Present Type...LEGO - Brand: LEGO Education - Target age: 6 years old and up - Accessories: Assembly guide - Number of parts: Various blocks and parts Thank you for viewing.
