Light-up LED guidance shoes, size 16. I couldn't capture the light-up effect well in photos, but both shoes light up. Battery life is unknown. They have not been used. There are stains inside. Please check the photos. They are priced accordingly. I didn't notice the stains until I inspected them, so they're not very noticeable and probably won't be seen when worn. - Brand: Disney - Model: LED Guidance Shoes - Color: Light Blue - Size: 16 - Features: Light-up function Please refrain from purchasing if you are sensitive to imperfections, as these have been inspected and stored by an amateur. Thank you for looking.
