Purchased on Facebook Marketplace on September 2nd, 2022. It came in its box, which is in surprisingly good condition, and with its spiral bound manual. It was missing its case, however I had the correct case from a lot of calculators I bought awhile ago that came with extra cases. I have not tested it as I dont have the batteries at the moment, but it was said to be functional last it was used.
