I've confirmed that it works, but sometimes it turns when going straight. After running it a few times, it goes straight. It's adorable how its eyes blink and light up red as it moves! Robot size (box size): Approximately 27cm There are areas where the color has changed due to aging, and the box is torn, so I've marked it as having scratches and dirt. Please understand that this is a used item, as it has been stored at home for a long time, and I have confirmed its operation.
