It is a 14-karat gold alloy with a total weight of 5% or more on the surface of the core material. Gold-filled is made with a thicker layer than gold plating, so it is unlikely to peel off even after long-term use. Generally, it contains almost none of the substances that commonly cause allergies. The clean shape gives a stylish impression.
