"Proto" series The series is named Proto, which means "early" or "prototype". With a simple design, it is a basic and minimalist series that does not dare to add design. The slightly larger hoop earrings created by the original are items that can be used both in mode and casually with the simplicity of the material. All of them are made of high-quality SILVER925 (sterling silver) material, so you can wear them for a long time. It is a simple and timeless series.
