The video shows a person's hand holding a black strap with a buckle. The person is seen adjusting the strap and then inserting it into a hole. The strap appears to be made of a durable material and is designed to be adjustable. The buckle is made of plastic and is used to secure the strap in place. The person's hand is visible throughout the video, and they seem to be demonstrating how to properly adjust and use the strap. The background is not visible, so it is unclear where the video was shot.
