Only the items shown in the images are included. There are no included accessories such as manuals. The year of manufacture is unknown. Please search for the detailed functions. The case is considerably deteriorated and produces black residue. Power was confirmed. Rotation in both left and right directions was also confirmed, but I cannot determine if the speed is normal. The condition is poor, so it is being sold as junk. Please understand and agree to the above before purchasing. Please note that I may not be able to respond immediately. #L14
