Please be sure to check the profile description. This is a Super Zeus toy from Bikkuriman. The main body size is approximately: Height: 4.5cm, Width: 3.5cm, Depth: 3cm. The mechanism is that you insert the included key (the one to the left of the main body in the photo) into the body and press the key-shaped knob to launch the main body. How about it, Bikkuriman fans? It's a very old item, so there is some damage in places. Please check the photos for the condition.
