20 alcohol breath tester machines , you put $2 in and blow on the straw to see if you have to much alcohol , more of a novelty item for man cave etc . missing keys about 5 are open not sure if they are all working but the ones we tried do . It was a running vending business that closed years ago and we purchased for the novelty of it . condition as don’t know much about them . Was told they were $900 each new . They light up and have sound . Some will definitely need a repaint /refurbishment There is a manual on how to calibrate etc
