The video shows a person's hand holding a stack of envelopes. The envelopes are white with black handwriting on them. The handwriting is not clear, but it appears to be a list of names and addresses. The envelopes have stamps on them, and one of them has a QR code. The person's hand flips through the envelopes, showing the front and back of each one. The video is shot in a close-up view, and the background is blurred.
