This is a well-regarded Sony product with basic functions, and despite its small size, the sound quality is good. It uses two AA batteries. It has all the basic functions, including record/playback, fast forward/rewind, counter, speed control, headphone jack, pause, and auto-stop, and they all work. The belt has been replaced with a high-precision one, and the speed has been adjusted. There are only a few scratches and stains. Overall, the appearance is clean, and the gloss on the front is like new. Cassette players are still convenient today, so please consider this one. Test batteries are included. Can be shipped with other items (200 yen discount, so please comment in advance)
