Thank you for viewing! This is an electric Caterpillar bulldozer purchased at Costco☆ It uses 3 AA batteries. When you press the red switch on the left, it vibrates and then moves forward. It's quite impressive☆ Also, the worker riding on it is also a switch, and each time you press it, music plays and it talks. Size: Length: Approximately 29cm ✖️ Width: Approximately 20cm ✖️ Height: Approximately 20cm There are small scratches here and there as the child played with it. Also, there is some rust on the battery pack, so although the operation has been confirmed, please refrain from purchasing if you are concerned. ※ I am also selling on other sites, so please check the stock in the comments. Thank you! o(^-^)o Toy genre: Electronic toys/Kids' electronics Gender: For boys
