In the video, a woman is seen holding a black strap with a carabiner attached to it. She is using her hands to demonstrate how to open and close the carabiner. The carabiner is made of metal and has a spring-loaded gate that can be opened and closed by pushing it up and down. The woman's nails are painted with a clear polish, and she is wearing a bracelet on her wrist. The background is blurred, but it appears to be an indoor setting with a wooden floor.
