Everything in the images is included. Year of manufacture and usage period are unknown. Please search for detailed functionality. I have lightly cleaned it, but due to the nature of the product, there may be shavings remaining. Please be sure to wash it. Replacing the blade is recommended. I confirmed continuous use for about 3 minutes after charging. There are no problems at the moment, but the degree of depletion of the built-in battery cannot be guaranteed. Please understand and agree to the above before purchasing. Please note that I may not be able to respond immediately. #L06
