Cardboard is shipped protected by cardboard and sleeves. Take it out of the packet and use it as a card protector. I was the only owner. Products are carefully shipped with a hard card protector sandwiched between cardboard. ** I have been collecting cards since 1992. Recently I decided to sell my entire card collection. These cards were obtained from the pack and I am the only owner. It has been protected by putting it in a sleeve for over 20 years.
