Using these sleeves is easy. Just slide your cards gently into the sleeves one by one. Make sure to align the card properly inside the sleeve for a perfect fit. When shuffling, these sleeves allow for a smooth shuffle, so you can enjoy your card games without any hassle. As for maintenance, keep them away from sharp objects to avoid tearing. Also, store them in a cool, dry place to prevent warping or damage. If they get dirty, you can use a soft, dry cloth to gently wipe them clean.
