Ok so can someone explain to me why I'm not supposed to remove this tag from the pillows I purchased that I clearly removed? lol Like for real, ladies you feel me, this stupid little tag is not cute when you're trying to decorate with some throw pillows. 

I've seen this on mattresses too. Do you remove them too or am I about to be in big trouble? I've never understood who, what, when, where or why? Why is this tag not supposed to be removed surely I'm not the only one 'breaking the law' here?
