RFID Blocking Sleeves, BLOCKIT Credit Card Review

I received this  RfID Blocking Sleeves to test and to give a review on it. It has a  Anti-Theft RFID Signal Blocking Protection Sleeves and it comes in several different colors. It is something in today's world that we need today because of people who try to steal people identities.  Because now a days they don't even have to swipe your card, they can just be near you and get your information so it is a good investment to protect your self.So this is made of  copper/aluminum material.  I do think they need to make the sleeve a little bigger than they have it because it is very hard to get in and of the sleeve. Also they need to make it denser material because it is easy to bend. I received this product for free for my unbiased opinion and my opinion is solely mine own.
