My child wore these shoes only on weekends because the daycare center doesn't allow light-up shoes. They are relatively clean and the lights work without any problems. They have been home-cleaned. When I washed them, some parts were difficult to dry and have left stains. The stains are marked with white circles in images 7 and 8, and there are similar stains on the sides in images 2 and 3. Please understand that these are items inspected and packaged by an amateur, stored at home. I may change the shipping method from Yu-Yu to Raku-Raku or vice versa.
