Thank you for viewing. This is a HITACHI wireless stereo KS-1000W. The size is 16cm high, 24cm wide, and 7cm deep. ・I checked the operation, and the radio reception worked fine, but the volume adjustment did not work. ・I checked the operation with only the power outlet and did not check the operation with batteries. ・As shown in photo 13, the sponge that holds the batteries (？) was crumbling, so I removed it. ・As shown in photos 14-19, there is a cover, but the condition is quite poor, so please understand. ・Please note that there are scratches and dirt as it is an old item. In addition, as I am ignorant of the product and there may be insufficient confirmation, I will list it as a "junk item," so please understand it as a "junk item."
