Believe it or not you are actually safer sending in a top loader with decoys then you are a magnetic. A magnetic breaks alot easier then a top loader believe it or not. A top loader is more flexible where a magnetic is stiff and would break just as easy as glass if dropped just right. Always use a flat rate box when sending high end especially graded high end. Those slabs are super safe if you are not moving the card from place to place. As soon as it starts to travel you risk it breaking. They have no give at all. Almost any impact will break or chip it.
