Cards are printed on paper on cardboard, the same material as an average jigsaw puzzle. Thanks for looking and supporting my small business. I source from liquidation warehouses, estate sales, and auctions. This means that I am able to purchase items at a cheaper price and pass the savings on to you. However, it also means that once the item is sold out, I am unlikely to be able to get it back in stock. Don't hesitate to buy when you see what you need so you don't miss out! Shipping only to the contiguous 48 states. Or international shipping through's Global Shipping Program. Returns are not accepted, so please inspect the photos carefully and ask questions prior to bidding. NOTE: I do my very best to provide you with clear and accurate photos and description of everything I sell. Please look at the photos and read the description carefully. If you have any questions, please let me know. I sure do appreciate it. Thanks!
