This is a TI-84 Plus graphics calculator from Texas Instruments. In the pictures, you see that the calculator requires 4 Triple A batteries, however the post office does not allow me to send batteries, so they are not included with your item. It is used, but in very good condition. My daughter only used it for one semester of college. No scratches on the screen, and minuscule scratches on the bottom. The USB cable is included, but not the instructions. Thank you for checking out my auction, check out the rest of my collectibles, and Happy Bidding.
