This is a Panasonic cassette tape recorder that I used at my parents' house. It's palm-sized and compact. Model number: RQ-L100 Size: Approximately 11.5cm x 9cm x 3.5cm I have confirmed that the recording, playback, fast forward, and rewind functions work. The fast listening function on the top switch does not work. There are no noticeable scratches or stains, and it is in clean condition. There is no box or instruction manual, but the instruction manual can be found in PDF format by searching on your smartphone. I plan to wrap it in bubble wrap and send it via Yu-Packet Post Mini.
