This coin holder is really easy to use. Just unzip the top to put your coins in and zip it back up to keep them safe. The front zip pocket with the key ring is great for holding small items or keys. To use it, simply unzip the front pocket and put your keys on the key ring. When it comes to maintenance, use a soft cloth to wipe the leather clean. Avoid getting it wet for long periods as it might damage the leather. If you notice any dirt inside, gently shake it out or use a small brush to clean it. And remember, the RFID blocking lining is there to protect your cards, so don't try to remove it.
