When you press the button, the time will be displayed. When you close the door and press start, the light will turn on and the plate inside will rotate. The button's function, the plate's rotation, and the light have been confirmed. The door was not originally designed to close securely. If the operation stops while playing, you can help the plate inside rotate by gently holding the door closed. There is a child's scribble on the top. There are also other minor scratches, so please understand this before purchasing.
