Using this Pokemon portfolio is easy. Simply open the portfolio and place your Pokemon cards into the pockets. You can single - load the cards for better access or double - load them to save space. When handling the portfolio, try to keep it away from sharp objects to prevent any damage to the pages. For maintenance, wipe it gently with a soft, dry cloth if it gets dirty. Store it in a cool, dry place to ensure the longevity of the acid - free, non - PVC materials. This portfolio is suitable for kids aged 6 and up, so adult supervision might be needed for younger users.
