Folding potty training seat with step (gray & white). Purchased about 2 years ago and kept in the toilet for about a month. It's lightweight, so children can set it up themselves. With the step, they could climb up and down on their own, making it easy to use without adult assistance, and toilet training went smoothly. After we stopped using it, I wiped it down with disinfectant wipes and stored it in a dark place. From the time of purchase, there are some white spots on the gray parts, which the manufacturer explained are a characteristic of the plastic. Please check the photos. There are no instructions. I wiped it down with a seat every time it was used in the toilet. I have wiped it with disinfectant wipes, but please understand that this is a used item. Thank you. #ToiletTraining #PottyTrainingSeat #WithStep
