Transcend 128GB SSD installed, 4GB RAM, comes with original pen. Touchscreen works perfectly, it's 12.5" -  no scratches - plastics are good, normal wear and tear - comes with Windows 10 Professional installed and activated. Its quite usable due to the SSD. All buttons work, including the tablet buttons that rotate the screen (windows 10 does not automatically rotate the screen on these Thinkpads). Battery holds a full charge. Comes with two original Lenovo AC adapters. Battery is a Lenovo Battery, its not aftermarket.

Its upgradable to a max of 8GB of RAM, which would make it faster. 

I used it for a project for my car and no longer need it, its ready for its new home! Ask any questions you like - if you are looking for a Thinkpad X220 Tablet you know what you are looking for :)
