These are light-up sneakers featuring Ariel from "The Little Mermaid." The size is 16cm. The instep strap is removable, allowing you to wash the shoes separately. My daughter loved wearing these, but she has outgrown them, so I am selling them. Please check the photos for the condition, as some parts of the strap and ribbon are torn, and there are marks from the left/right identification stickers on the insoles. There is some dirt from use, but the lights still work, so I think they can still be worn. Please understand that these are pre-owned items and have been inspected by a non-professional before purchasing. I am also selling other baby goods and children's clothing. Discounts are available if you purchase multiple items, so please take a look.
