Thank you for viewing. These are cute car-design knee supports for babies. I believe they were used only a few times. There are no noticeable stains or tears, and they are in generally clean condition. How about these for protecting your baby's knees when they start walking or are prone to falling? They are made of soft material and are easy to use daily. These are used items that my child has worn, so I would appreciate it if someone who understands this would like to purchase them. Thank you very much.
