Realistic Radio Shack Voice-Operated Hands-Free 5-Channel Walkie-Talkies 21-407

Realistic Radio Shack Voice-Operated Hands-Free 5-Channel Walkie-Talkies 21-407 Listed as For Parts or Not Working because these are untested. They appear to have little or no use whatsoever, BUT, the styrofoam packaging has started to degrade and stick to the units a bit (ZOOM IN on pics to gauge condition). These might work, who knows?
