Using this card holder is a breeze. Simply slide your cards into the three slots and if you have a photo you want to display, put it in the clear pouch. When it comes to maintenance, keep it away from sharp objects to avoid scratches on the PU material. Wipe it with a soft, dry cloth regularly to keep it looking its best. Don't overstuff the card slots as it may damage the holder. It's suitable for daily use, whether you're at school, work, or traveling.
