thomas and friends mini series

all my packs get opened too, but i used to keep the mattel disney pixar cars MOC, and remember the hunt to find perfect cards well. although, some cars were so hard to find that sometimes the card issue was ignored.
i have seen bent cars cards come out of the original shipping boxes, so my guess is the people who pack them being fast and not taking care... they are "kids toys" after all, the kids dont care about the condition of the pack. i also recall hearing about the workers of the stores deliberately bending or tearing cards.
