I work in the medical field so I'm lucky to snatch a few from work. You can buy them on Amazon aslo: https://www.amazon.com/Vestil-SECS-...8&qid=1472675943&sr=8-1&keywords=security+tag
I always wondered why people think these security tags will protect them from scammers or the ones who like to "borrow" things. If someone decides to return the bag cause it's not as described, I am sure Tradesy (and eBay) will make it happen even without security tag on it. It's not me who's making the decision whether to accept return or not in this case. I was thinking of using them, but does it really make any sense? Same with videotaping the process of shipment / packaging. It doesn't work as it's impossible to prove that you didn't replace an item after you stopped videotaping. These things don't protect us agains scam unfortunately
