In the video, a person is seen holding a black diving mask in their hands. The mask appears to be made of rubber and has a black strap attached to it. The person is standing in front of a sink, and they are using their fingers to clean the mask. They are carefully removing any dirt or debris that may have accumulated on the mask's surface. The sink is white, and there is a mirror above it. The person's movements are deliberate and precise as they ensure that the mask is thoroughly cleaned.
