● This is a listing for a set of 2 remote controls for Panasonic portable CD players. ※SL-CT440, 490, 520 SX482, 332, SX289L, SL-S230, etc. ● Since I don't have the main unit, I haven't confirmed the button operations, but I was able to confirm that sound comes out with my own headphones. ● There are scratches, dirt, and scuffs. ● This listing is for the remote controls only. ● Immediate purchase is possible.
