Karla, one of the strongest girls in our site and we ever met. We gave she an old sturdy notebook, it is thick and resistant. She goes directly to the action, without flexing her big and boulder biceps. Her arms are so strong that she rips and breaks the screen without any complication. Sometimes she punches that notebook just to release some her anger. She tears the screen apart, breaking it in several pieces. Then she goes for the body. Is very strong and resistant, but those big biceps are not just for demonstration. She tears that notebook body in pieces leaving a path of destruction.
