Using these sleeves is super easy. Just gently slide your cards into the sleeves one by one. This will not only protect them from scratches and wear but also add a cool look to your collection. When shuffling, you'll notice how smoothly the cards move thanks to the excellent design. As for maintenance, keep them away from sharp objects and excessive moisture. If they get dirty, you can use a soft, dry cloth to gently wipe them. That way, your sleeves will stay in great condition for a long time and keep your cards safe.
