Carry-on size, mini, beige, ride-on suitcase

Kids Travel Carry Mini (Carry-on OK, 32L)
I purchased this item in beautiful condition, having been used only once about 4-5 months ago, and I used it once for a domestic trip. My child enjoyed riding on it at first, but then wanted to walk, so they didn't ride on it much.
I believe major airlines like ANA and JAL allow carry-on within their size regulations. Due to circumstances, I checked it as baggage on the way back, and it ended up with scratches and dirt all over (it was used with almost no scratches and in clean condition until then).
*Please see photos 6 onwards.

Although there are dirt and scratches on the exterior, it has only been used twice, so there are no issues with the casters or hardware, and the interior is clean. I have cleaned off any removable dirt.
This carry-on case can be used by children up to 6 years old, making it recommended for children who don't walk much or for conserving energy during trips. Also, regarding luggage, it can hold all the luggage for 2 nights and 3 days for myself and my child, giving the impression that it holds quite a lot.

This is a pre-owned item with scratches and dirt. Please understand this point before purchasing.
It will be shipped wrapped in bubble wrap.
