These metallic handphone novelty bags are super easy to use. Just open the bag and put your phone or other small items inside. When you're done, close it up and carry it around. As for maintenance, use a soft, dry cloth to gently wipe the surface if it gets dirty. Don't use any harsh chemicals as they might damage the bag. And remember, due to the presence of chemicals like lead and cadmium, avoid letting children play with it in an unregulated way. Keep it in a cool, dry place when not in use to keep it in good condition.
