This is an electric toothbrush for children. I bought it a few years ago and used it two or three times, but it has been stored at home since my child didn't like it at the time. The brush that came with the main unit has been used and is not included. The replacement brushes are unused. The operation has been confirmed, and the batteries are still inside.
