I am selling some parts because I bought them used, but I don't need them. I wiped off the dirt with a disinfectant sheet, but there are some stains that couldn't be removed, as well as scratches and minor imperfections. Also, there is no non-slip material. One of them seems to wobble when placed on a flat surface, but I think it will be fine to use it attached to a playpen. Please check the photos for the condition of the product. Please refrain from purchasing if you are concerned, as this is a used item and has been stored by a private individual. I will wrap it in cushioning material and put it in a cardboard box for shipping, assembled as shown in the last photo. #Caraz
