To use this wallet, simply slide your cards into the card slots and put your notes in the note pockets. For your coins, open the change pocket by unfastening the stud and drop them in. When it comes to cleaning, use a soft, damp cloth to gently wipe the surface. Avoid using harsh chemicals as they might damage the PU material. Keep it away from sharp objects to prevent scratches. Also, don't overstuff the wallet to maintain its shape and functionality.
