In case you clicked on this by mistake, we want to be clear. This product is meant to be used on fingerboards. You know teeny tiny skateboards for your fingers. NOT full size skateboards. The ramp will not come with the metal piece on the bottom, BlackRiver sands their ramps to perfection, so the metal piece is no longer included.
