After cutting filing etc., nose pads are cut and fixed with solution and kept for drying. Before fixing of nose pads, the front piece is put in moderately hot water and bent to the required shape on hand press. Then they are put in barrel for polishing. Hinges and Pins are fitted and riveted. Again lots of a few dozen pieces are put for lustre polishing.
