Using these sleeves is easy. Just slide your trading cards into the sleeves one by one. Make sure to align the card properly to ensure full protection. When shuffling, the sleeves will give you a smooth and enjoyable feel. As for maintenance, keep them away from sharp objects that could tear the sleeves. Store them in a cool, dry place to prevent any warping or damage. Avoid exposing them to direct sunlight for long periods as this might fade the vibrant colours. These sleeves are designed to last, but gentle handling will keep them in great shape for all your future card games.
