The box or outer packaging may be less than perfect and it will have been opened for picture taking purposes. This does not mean it is used or defective. The part may have been made by a different manufacturer than they use today and it may not look the same as a new retail one from the dealership. It may have been re-boxed and returned. This does not mean it is not an OEM part. It just means it was made in a different time period by a different manufacturer.
