This set includes everything in the photos, including the Bunbun Supercar. The assembly instructions are a similar version downloaded from a website; the original is not included. As shown in the photos, it can transform into a trailer and a robot. Even I, a clumsy mom, could do it! The outer box is included. Since the assembly instructions are not the original, the price has been reduced accordingly. No claims or returns, please. Thank you for looking.
