Korean Chopsticks - Stainless Steel These are metal chopsticks I received as a souvenir from Korea a long time ago. They have a crane or heron pattern, a "18-10" marking, and a "S.I.S" marking, which I'm not sure if it's the manufacturer. They are flat, not round. They are unused, but there is no box. They were bundled together with other unused cutlery. They appear to be in good condition at first glance, but as they have been stored at home for a long time, there may be some overlooked imperfections.
