Using this Gamegenic Casual Card Collecting Album is a breeze. Simply open the album by loosening the elastic strap. Slide your standard or Japanese-sized collectible cards into the side-loading pockets one by one. You can easily fit up to 360 cards, even if they're double - sleeved. When you're done adding cards, tighten the elastic strap to keep the album closed and your cards safe. As for maintenance, keep the album in a dry place to prevent the PP - material from getting damaged. Avoid exposing it to extreme temperatures. If it gets dirty, you can gently wipe it with a soft, dry cloth. Remember not to force too many cards into the pockets to avoid tearing the material.
