To use these sleeves, simply slide your cards into them one by one. This will not only protect your cards from scratches and dirt but also enhance your game experience. When handling the sleeved cards, make sure to keep your hands clean to avoid leaving fingerprints on the clear front. For maintenance, you can gently wipe the sleeves with a soft, dry cloth if they get dirty. Store them in a cool, dry place away from direct sunlight to prevent any damage to the color or texture. Enjoy playing with your well - protected cards!
