The video shows a person's hands holding a black smartphone and a clear phone case. The person is demonstrating how to put the case on the phone. They first place the phone face down on the table and then pick it up. They then slide the case onto the phone, making sure it fits properly. Once the case is on, the person picks up the phone and turns it over to show the back. They then press on the case to demonstrate its flexibility. Finally, they flip the phone over to show the front screen.
