Tested works great! It does have label of previous owner on inside of case and back of calculator as seen in pictures!

Please look carefully at the shipping time frame shown on the listing. Your item will arrive in the shipping time frame. Baked into that shipping time frame is a 6 day handling time because I can often only get to the post office once a week. People who are used to prime panic sometimes when an item has not shipped with in a day or 2, I assure you your item will get to you with in the shipping timeframe listed.  Condition is as is seen in pictures!
