Panasonic 24 Button 3 Line Digital LCD Display Phone KX-DT543 Black

Bought these from a garage sale and im not able to test them but the person i had bought from told me they are in working condition and just didnt need these. All of them appear to be in good condition, some of the phones are do have some scratches on them but the telephone system are in great condition. I have 8 of them currently, i will return these if they don’t work
