Please refrain from bidding if you cannot accept imperfections not visible in the photos—such as edge whitening, scratches, peeling, creases, bends, or dents—or if you are seeking a flawless, mint-condition item. Since these are cards from decades ago, they may have factory-origin flaws or signs of aging (such as discoloration); please examine the photos carefully. -------------------------------------- Import duties, taxes, and charges are not included in the item price or shipping cost. These charges are the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to bidding or buying. Please note that international shipping may take longer due to customs clearance or local postal situations. If you have a VAT number or taxpayer number, please let us know after you make a successful bid. This may prevent the item from being properly cleared by customs.
