This project was come from the CNC Machining PC workpiece and polished with sandpaper range from 240# to 400# to 600# to 800# to 1000# to 1200# to 1500#,you can hardly found any scratches on the surface which makes it crystal clear and beautiful. Although it need quite a lot of handwork but worthwhile. Finally we made it another copy from silicone mold(Silicone tooling/vacuum casting). Leadtime 8 days.
