This is the most awesome "Optimus Prime" mecha work I have ever seen. More than 200 sets of grouped molds are made of more than one ton of materials. It took 2 years to complete. Use the word "Niu B" to describe it. The overall size is 75*40*40cm, the net weight is 18~26 kg, and the gross weight is 30 kg. It is made of all-metal bronze. It is not the kind of spray-painted plastic model that can compare with the United States, and the manufacturing cost is estimated to be terrifyingly high.
