In the video, a person is seen holding a small doll's hand and arm. The hand is white and appears to be made of plastic. The person is holding the hand between their fingers and moving it around, possibly to show the flexibility and range of motion of the joints. The arm is also white and has a circular joint at the end, which allows it to be attached to the body of the doll. The person's hand is visible throughout the video, and they seem to be examining the doll's hand and arm closely.
