This item was given to me by a friend. I used it for about a month. In the fourth photo, a sound is produced when the button is pressed. It is very effective for toilet training. For those who don't mind used items. This is a hygiene product. It has been disinfected with alcohol. The batteries will be included when shipped. Since this is a casual inspection, there may be oversights. Please refrain from purchasing if you are nervous about used children's items or if you are looking for a perfect item. No box included.
