This is a Showa-retro CASIO calculator. It's an early calculator with a memory function, displaying numbers on a fluorescent display tube, predating LCDs. It uses two AA batteries (alkaline batteries included). The main body has no noticeable scratches, but it's a product from nearly 40 years ago, so there is some minor wear and tear. Above all, the design is wonderful, and I used it from time to time. Please make good use of it.
