Using this Twin Star PHONE POCKET ID is easy. First, choose your favorite mementos or pictures and place them in the Polaroid - style frame. You can also attach cute charms or trinkets to make it even more unique. When using it with your phone, make sure your smartphone case doesn't have an open bottom, as it won't work in that case. Also, check the shape of the charging port of your smartphone case, as it might affect usability. To keep it in good condition, avoid exposing it to sharp objects or excessive moisture. Just a gentle wipe with a soft cloth will help maintain its charm.
