HAPPY NEW YEAR

My friend loves to shoplift so they got me an anti security tag thing. And I’m a little confused about how to use it. <br><br>What color is the side of it where you actually put it on the item? <br><br>Can you get caught with it? (It’s like similar to a hair clip, a bit smaller than one) <br><br>How do I put the anti security tag on an item/ how do you get it to actually look like it’s a tag vs just a hair clip on the item? <br><br>Or is it only for clothes?
