Using this wallet is super easy. Just unzip the shiny gunmetal - colored hardware to access the four card slots for your cards and the clear slot for your ID. Zip it up to keep your valuables safe. When it comes to maintenance, use a soft, dry cloth to gently wipe off any dirt or dust. Avoid getting it wet as it's made of vegan leather (polyurethane). Don't overstuff the wallet to prevent damage to the zippers and the structure. Keep it away from sharp objects to avoid scratches on the debossed appliques and prints. With proper care, your Loungefly Demon Slayer Group Zip - Around Wallet will stay in great shape for a long time.
