How to use: First, take out all the parts from the kit. Assemble Duke in ambulance mode according to the instructions. Then, transform it into robot form by following the transformation steps. Next, merge it with Fire Loader to get Duke Fire. If you have the separately - sold SMP J - Decker, you can combine them to form Fire J - Decker. Note: Be careful when handling small parts to avoid losing them. Read the assembly instructions carefully before you start. Maintenance advice: Keep the model in a dry and clean place. Avoid exposing it to direct sunlight for a long time, which may cause the colors to fade. If there is dust on the model, you can use a soft brush to gently clean it.
