This is a SONY cassette player. It has some minor scratches on the surface due to home storage. The following maintenance was performed to ensure proper cassette playback: * Replacement with high-quality rubber belts * Cleaning of the head and pinch roller * Application of contact spray to contact points * Circuit board cleaning * Cleaning of gears and internal components Although maintenance was performed, the gum battery terminals have rust, so gum batteries cannot be used. Playback was tested using a dry cell battery case, and all functions such as playback, fast forward, and rewind were confirmed to work. There is no severe sound fluctuation, and I believe it can play music normally. The remote control also works without any problems. In the unlikely event that it does not work, I will accept returns and refunds. Please note that you will need separate dry cell batteries to use it. Shipping will be via Yu-Packet Post.
