Using these Dragon Shield Dual Matte sleeves is a breeze. Just gently slide your TCG cards into the sleeves one by one. For best results, make sure your hands are clean to avoid leaving any fingerprints or dirt on the sleeves. When shuffling, the textured back provides a great grip, making it easy to mix up your cards. As for storage, you can use the cardboard box that comes with the sleeves to keep your sleeved cards organized. Keep the box in a cool, dry place away from direct sunlight to prevent any damage to the sleeves or cards. If the sleeves get dirty, you can use a soft, dry cloth to gently wipe them clean. Enjoy your TCG with these high - quality sleeves!
