Thank you for viewing! This is something I used for three years during my high school days! I'm not sure how to check the detailed specifications, so I would appreciate it if you could judge from the images. I apologize. From what I can see, it has 4GB of memory and 64GB of storage! I have done a basic cleaning, and I will also include a cleaning kit, so please feel free to use it if you are concerned. There are some sticker residue marks in places, so please purchase only if you can accept this! One side of the keyboard connection is detached, but I have confirmed that it works. I have also updated the main unit to the latest state, but the feel of use may be different from what some people imagine, so please understand that this is a used item. We do not accept returns or exchanges to prevent any trouble. The charging cable is not included. Only the items in the images are included. Please feel free to ask if you have any other questions. I have already packed it, so it is ready to ship immediately, but I am sorry that it is difficult to add more photos...
