This handsome piece is vintage circa 1920’s/30’s. It’s white gold on the case and the knives are some kind of metal. It measures 2 1/2 x 3/8 inches and the blades fit into the case. The case holds up to 10k acid and the loop which allows you to put this on a chain is stamped "Gold Top". The condition is very good with no rust on the knife blades.
