The cards have been stored in sleeves. Please understand that since I haven't done a detailed inspection of each card, they are all treated as having some scratches or stains. *Personally, when I quickly looked them over for listing, I thought the overall condition was good (that's why I've listed them as having some scratches or stains). I will not use cardboard for bending protection. I will put them together in a bag, wrap them in bubble wrap, and then put them in an envelope for shipping. Management F-3
