K14gf is a gold-plated process where 14-karat gold accounts for 1/20 of the total weight. It is pressed firmly, so it rarely peels off even after long use. Because it allows you to easily enjoy the luxurious shine of gold, many brands in Europe and America use it as a genuine jewelry material.
Also, since it is nickel-free, it is a material less likely to cause allergies, so those with metal allergies can use it with relatively more peace of mind.
