In the video, a person is seen wearing a white, mesh-like sleeve on their arm. The sleeve appears to be made of a flexible material with a honeycomb-like pattern. The person's hand is moving around inside the sleeve, touching and feeling the material. The sleeve covers the person's arm entirely, and the hand can be seen moving in various positions within the sleeve. The person's movements are slow and deliberate, allowing for a clear view of the sleeve's texture and flexibility.
