Purchased from Threeppy (3COINS) approximately 2-3 years ago. I'm selling it because I never had the chance to use it. I only took it out once and haven't used it at all. No stains or scratches. (I remember it was sold in a white bag like the one in the image) The back has a non-slip surface. Recommended for those who go out often ◎ Good for potty training ◎ Although it's unused, please understand that it has been stored at home for a long time.
