What do I do with curling foils?
Unfortunately, due to weather conditions and changing temperatures, it is possible for Foil cards specifically to become warped in transit. We've found that placing the cards inside of a hefty hardcover book and then adding a few extra books on top for a couple of days usually straightens out cards that are warped.
Foils have a tendency to warp naturally -- it is not uncommon to have a foil that went directly from the pack to a top loader to have a slight warp.
Our shipping team has been working on some alternative shipping methods for foils to help reduce the tendency for cards to warp in transit. We also keep in mind the natural warping tendencies when storing our cards to help mitigate the curling.
If the methods above are not able to resolve your issue, please contact the seller by accessing your Order History and selecting the “Contact Seller” button next to the associated order. Curling foils are treated as a condition issue, and sellers will work with you according to our Refund and Return policy to resolve issues with them.
