Here's a forensic description of the video: A manicurist wearing black gloves uses a blue electric file on a client's fingernail. Both hands are covered in white dust. The nail is being prepped for some form of application, possible gel. The client's hand is resting on a metal grate or mesh surface. The manicurist is wearing a black tank top with a patterned skirt or pants and appears to be working in a nail salon. The manicurist's face is not visible.
