This was used when my son was afraid to sleep alone. The transparent sphere on the left projects colorful, wave-like light, and the cylindrical part on the right projects images selected from the film. There are six types of film. One type has a pattern that my son set himself. I've also included reference images, but there's no 3D effect like a hologram. It's just projected onto the ceiling and walls. It also has a timer and brightness adjustment. If you don't use the film, it can also be used as a room light. To get you started right away, I'll include a 100-yen shop adapter for the power outlet. Please consider purchasing only if you are not concerned about the current condition. I will pack it carefully to prevent damage, so I cannot offer a discount due to shipping costs, etc.
