Hi I am wondering if attaching the MagSafe duo to metal would some how mess it up. This in turn would work like a magnet. I am trying to make a makeshift stand for my iPhone to use with the standby feature. So I will be using a metal box and and folding the iPhone portion up and then attaching the iPhone on it so it is facing me when I sleep. It looks really good. I’m just wondering like I said if it will damage my phone or the MagSafe due at all. Thanks for your help! Have a great day!
