This is an original product of Kiwa Seisakusho. It has a gentle curve. The size of the ring is small and hard to stand out, so it is recommended for delicate designs. Round rings and C rings with a wire diameter of 1.0 mm or less can be used. Use it as an accent by placing it between chains or parts. *As this is an accessory, the color may change to reflect changes in fashion. Also, during the processing process, color shading may occur without prior notice. Please note. (Some parts may differ in color from other parts.)
