The material is brass. Use charms and large parts to pendant tops. Please use it through chains. The Vatican part can be opened and closed, so you can connect the ring -shaped parts directly by reverse up and down. * Please note that applying unreasonable force or repeating the opening and closing of cans may cause the plating to peel off or damage. * Because it is an accessory, the color may be changed by incorporating the trendy change. In the processing process, shades of colors may occur without notice. Please note. (Depending on the parts, there may be a variation in color with other parts.)
