Unlike regular gold plating (GP: Gold Plated), 14kgf uses an alloy such as brass as its core metal, and coats it with an alloy containing gold that makes up 1/20 (5%) of the total weight. The gold coating layer is 20-30 times thicker, and is coated with heat and pressure, making it more durable. It is also known as "gold-filled". Unlike gold plating, there is almost no worry of the plating peeling off quickly. It is a material that allows you to easily enjoy the shine of real gold. As it is a natural stone, there may be inclusions, small scratches, chips, and dents, but please understand that this is a natural characteristic. The color may appear different depending on the device you are using. Please understand.
