These forks were handed down from my Korean grandmother (Harmony). You will see from the photos they are stamped, numbered and "guaranteed" to be sterling silver.
The box has wear and tear from moving from Japan to Korea and all over the US. The box is numbered 0916. Hinged box with velvet interior. Each fork is stamped sterling.This set was never used and was collected in the box. We have owned these for 100 years in one family. If you love Asian art this set is for you. Good luck and thanks for looking.
