Awesome rare clear TI-83 Silver Edition. Tested Working. Perfect calculator for advance graphing and other tasks. Disclaimer: As with any worn/ used item, unnoticed flaws may be present. Item has been briefly cleaned. Further cleaning may be required as the item may be dusty/have lint/hair, debris, etc. from storage. As my items are second-hand finds for the most part, they are all subject to different people's detergents, fabric softeners, and household pets. While I make a point to remove as much as possible of these variables, I suggest that if you are overly sensitive to any of these factors that, you may want to consider professional cleaning of the item prior to use. I make every effort to ship the same or next available ship day to get you your item as quickly as possible.
