This is a potty training seat purchased here (Mercari). I purchased it in good condition and used it for about six months. I believe there are no noticeable scratches on the seat itself. The tips of the non-slip feet are slightly bent from being leaned against something, but there is no problem with use. I plan to wash it thoroughly, disinfect it with alcohol, and disassemble it before sending it. There are no instructions or box, but it was easy to assemble by looking at the photos. The following is an excerpt: ● Material: Seat frame: Polypropylene (other frame ABS resin) Seat cushion: Non-phthalate vinyl chloride Non-slip: Thermoplastic elastomer ● Size: Width 40cm x Depth 55cm x Height 55cm ● Suitable age: Approximately 1 to 3 years old (up to 35kg) ※ The step or the screws for adjusting the seat frame are already included with the main unit. ● Compatible toilet size: Inner diameter of the toilet seat: Width 21-24cm Depth: 25cm or more Height from the floor to the toilet seat: 41-45.5cm 【Features】 From KARIBU, a folding toilet trainer. It's foldable, making it convenient to carry and use when you're out and about. It has rubber non-slip feet for peace of mind! The cute animal pattern design might make going to the toilet more fun.
