I am not an expert, so this item is being sold "as is" with no confirmed functionality. There are markings on the case. Everything in the photos is included. Please understand that this is an "as is" sale before purchasing. Also, as this item was received from someone else, I do not know the purchase date or how often it was used. I have cleaned it simply, but it is a used item, so there may be remaining dirt or scratches. Please refrain from purchasing if you are looking for a perfect item or are concerned about these issues. To prevent any problems, please comment if you have any questions.
