In the video, a person is seen using a knife to cut open a cardboard box. The person's hand is visible, and they are using the knife to make an incision in the box. The box appears to be a standard brown cardboard box, and the knife is a standard kitchen knife with a silver blade and a black handle. The person's hand is steady as they cut through the cardboard, and the knife moves smoothly through the material. The background is not visible, so it is unclear where the box is located or what is inside it.
