This is an educational toy that allows you to build courses with Doraemon's secret gadget switches and blocks, helping to develop logical thinking skills. One long rail is missing, but it seems you can still build the courses shown in the instructions. What I can offer are the parts in the first and second photos, and the instruction manual from the third photo onwards. There is no box. Since this was played with by a child, there may be some dirt and scratches. I would appreciate it if you could purchase it understanding that it is a used item. 【About the product】 Build a course with switches and blocks and deliver the ball to Doraemon at the goal! When the ball rolls, Doraemon's secret gadget switches activate! This is a voluminous kit with many original switches, such as the "Anywhere Door" that warps the ball from bottom to top, the "Take-copter" that spins when the ball passes through, and the "Time Tunnel" where the ball wanders through time and space. Furthermore, it can be combined with the previously released Koroga Switch series, further expanding the range of play. By playing and going through the four flows of "thinking," "building," "trying," and "fixing," you can acquire the programming-like thinking that is the basis of programming learning. Thank you for viewing. Type...Blocks
