This item was obtained as a prize about 20 years ago. I used it a few times back then and then stored it in a chest. I have checked the operation. (There is a motor, so the dome inside should move, but it doesn't seem to work, perhaps I'm doing something wrong. If anyone knows how, please try it.) The second photo is of the ceiling. There are no instructions. To put it simply, ① Remove the lid ② Turn the switch ON and you can enjoy it. ※ The light will not turn on if the switch is turned ON while the lid is closed. ※ The light will turn off if you close the lid while the switch is ON.
