Item comes from a smoke and pet free home. Buyer will receive everything as is. The calculator functions properly. But its battery needs to be replaced. So it will shut off quickly. If it is not, directly plugged into its power source. And it also has some. Natural wear that is shown in the pictures. However its case and a charger are also included. Feel free to message with any questions. I am also very open to offers. So don't hesitate to ask. Thank you
