Using this cute hedgehog mobile phone chest bag is a breeze. You can carry it around for your daily activities like going out for a walk or commuting to work. Just put your phone and other small items into the four compartments. When it comes to the lanyard, you can attach or remove it as you like, but be gentle to avoid any damage. For storage, find a dry place to keep it. If it gets dirty, wipe it with a damp cloth. And remember, don't leave it under the sun for too long, as that might harm the material.
