The shop was soo incredibly high precision, if there was just the littlest imperfection, they would replace their Jaws. The # 1J thru 6J are in super good shape with hardly any imperfections. The 7J thru 10J have a little more issues (send and honest offer for those. Please message us what set Number you are choosing (we will say at the end of our description what one(s) are sold.). We even drew-up a dimensional Diagram to make sure the measurements are correct for you. Please look the pictures over, we are showing the worst of any issues.
