In the video, a person is holding a yellow and black phone case in their hand. The person is using their thumb to push down on a button located on the back of the case. The button appears to be a locking mechanism that secures the case onto the phone. The person then proceeds to slide the phone case onto the back of a phone, demonstrating how the case can be easily attached and removed. The case seems to fit snugly around the phone, providing protection and a secure grip. The person then rotates the phone to show the sides of the case, which have a smooth finish and are free of any visible defects. Overall, the video provides a clear demonstration of how to use and attach the phone case to a phone.
