This is a Richell potty training seat. I purchased it around September 2024 and used it for about six months. I used it by placing it directly on the toilet seat, so the fixing attachments are unused. There are no noticeable stains, but I found one scratch during inspection (see photo 7). I didn't use it in a way that would cause scratches, so I think it was probably there from when I bought it. I don't think it will cause any problems with use. There were no scratches on the toilet seat I used it with. I will disinfect it with alcohol and wrap the box in plastic before shipping.
