Using these Gamegenic Slide Card Cases is super easy. Just slide open the case, place your trading card inside, and then slide it closed. When choosing which card to put in, make sure it's a standard - size trading card, and it can have an inner sleeve on it too. For maintenance, keep the cases in a cool and dry place. Avoid exposing them to direct sunlight for long periods as this might affect the UV protection. Also, don't use sharp objects on the cases as it could scratch them and reduce clarity. If they get dirty, you can gently wipe them with a soft, dry cloth.
