Using these card sleeves is easy. Just gently slide your trading cards into the sleeves one by one. Make sure to insert them straight to avoid any creases. When shuffling, the textured back of the sleeves gives you a great grip, so enjoy a smooth shuffle experience. As for care, keep them away from sharp objects to prevent tears. If they get dirty, you can use a soft, dry cloth to wipe them clean. Store them in a cool, dry place to maintain their quality. Also, don't expose them to direct sunlight for long periods as it might fade the artwork. With proper use and care, these sleeves will protect your cards for a long time.
