In the video, a man is seen sitting in the trunk of a yellow car. He then proceeds to pull out a black folding shelf from the trunk. The man then unfolds the shelf and sets it up, demonstrating how it can be used to create a flat surface in the trunk of the car. The shelf appears to be made of a sturdy material and is designed to fit snugly in the trunk. The man then folds the shelf back up and places it back in the trunk, showing how it can be easily stored away when not in use.
