Potty Training Seat Rozally With Step/Foldable I used it for about a year. There are some stains as shown in images 6 and 7. Thank you for your understanding. *Alcohol-sterilized The screws on the step tend to loosen, so you will need to tighten them periodically. (This is not a malfunction) It will be wrapped in cushioning material and shipped in a spare cardboard box I have at home. Please note that there may be sudden changes (I will basically report them after the fact). If you have any questions, please feel free to comment^^
