This is a remote control for a Panasonic compact stereo system. Model number: SC-HC300 I am selling it because I don't use it. Although it is unopened, I tested its operation once from the outside of the bag. It worked without any problems. I purchased it new 4 years ago. There are no accessories. There is writing on the bag. I hope you will consider it. ※For your reference, I have included a part of the instruction manual. - Brand: Panasonic - Model Name: Audio Remote Control - Condition: Unused Thank you for looking.
