These are light-up roller shoes! They are size 22-22.5cm (see the insole in photo 12). They are in excellent condition, only tried on indoors. I'm selling them because the size didn't fit! Perfect for a Christmas present ♡ There's a cable and button inside the Velcro straps. Off → On → Flashing → Fast flashing. You can push the button on the back while putting the rollers in and out of the heel. The rollers can also be removed, and they come with a cover, special tool, and a USB charging cable. There are some creases from storage. Please refrain from purchasing if you are sensitive to this.
