Unlike regular gold plating (GP: Gold Plated), 14kgf uses a metal alloy such as brass as the core, and coats it with a gold alloy that contains 1/20 (5%) of the total weight of gold. The gold coating layer is 20-30 times thicker, and is coated with heat and pressure, making it highly durable, and is called "gold filled". There is almost no worry of the plating peeling off quickly like gold plating. It is a material that allows you to easily enjoy the shine of real gold.
