I purchased these at Toys "R" Us about 5 years ago. I'm selling them because my child has outgrown them. They fit sizes 21-23.5cm. A set of knee, elbow, and palm protectors are included. All items have scratches and stains as they were used by children. The tip of the left shoe's lace has been cut, so it's shorter than the right one. I don't think it affects functionality.
