In the video, a person is seen holding a black seat belt buckle. The buckle is attached to a metal bar, which is part of a car's seat belt mechanism. The person is demonstrating how the buckle can be adjusted to fit different positions. The buckle is made of black plastic and has a silver metal bar that attaches it to the car's seat belt mechanism. The person's hand is visible as they manipulate the buckle, showing how it can be moved up and down to fit different positions. The background is blurred, but it appears to be the interior of a car.
