This is a Panasonic portable CD player, model SL-S270, purchased in 1997. It has hardly been used. It's a rare item with the original box. Everything included is shown in the photos. The main unit is in good condition for something that's about 30 years old. The box shows signs of aging, so I've marked it as "used with scratches and dirt." I've confirmed that it runs on AA batteries. The remote control function has also been confirmed. The original earphones have sound distortion. New batteries are also included.
