3pk Green State Contour Mini 2 Step Medium (gray) / Ultra Fine (white) 7x 19mm
The #501 silicone wheel should be used for gross reduction, followed by the GS Contour tool at low rpm. This is a “finessing tool” for obtaining perfection of restoration.
The larger gray segment of this new and unique tool quickly reduces the larger final mass of the sprue with minimal risk for damage to the green state ZR.
