Physical design permits clean extraction of high quality collectible cards that have been sent in the mail.
Embedded, inset cards are protected from edge damage that is possible in the US mail. Micro-perforations separate leaving clean edges. Proper trading card layout in the postcard minimizes marking risks over the trading card. Plus, the post office does not “cancel” postage when the cards are pre-printed with postal compliant addressing, bar-coding, and indicia. Such pre-printing is standard with Insetcards postcards.
