Thank you for viewing. This is a SONY laptop, VAIO VJF156. I am not familiar with the specifications, so I have taken pictures of the instruction manual. Please check the 11th image. The items for sale are all shown in the 10th image. It has Windows 10. There is a product key card for Microsoft Office Home & Business Premium. (It seems it only works with the account that was initially registered. Therefore, it is likely unusable.) The main unit has been initialized. When purchasing, please understand that this is a used item and accept it as-is, with no claims or returns.
