What in the world!?! I've packed cards between toploaders like this before, but how is it not common sense that they need to be tight enough so that the card can't move? Also, did they just toss it in a mailer like that? I usually wrap my cards in an extra layer of bubble wrap, even if they're all in toploaders and team bags.
The way people pack/ship cards never ceases to amaze me! You'd think there were no articles, or complaints, anywhere on the internet explaining to people the importance of practicing good packing/shipping of cards.
