How to use: Simply zip up the bag, put your things inside like your phone, wallet, and keys. Then, wear it across your chest for easy access. Notice: Don't overfill the bag as it may affect the zip's durability. Try to keep it away from sharp objects to avoid scratches. Maintenance: Use a soft cloth to wipe the bag regularly. If it gets dirty, you can use a mild leather cleaner to clean it gently.
