Pinza teaches your cords to be more considerate and looks good doing it. Pinzas are cast from solid stainless steel and hand polished. They are incredibly easy to use. Slide the black band on the right side off and run your cords through. To adjust the amount of cord in front of the Pinza, just pull on the cord. The Pinza will rotate up allowing the cord to slide through. When you stop pulling, the Pinza will rotate back down, pinning the cord and holding it in place.
