This was given to my mother as an engagement gift about 30 years ago by an acquaintance from China, but it has been stored unused in a warehouse. Each item is in its own presentation box. One pair of chopsticks is stamped with "Pure Silver" and "99.98," and since they were received at the same time, the other pair is likely the same. Please note that some rust is visible due to long-term storage (please check the photos).
