These are stopper findings from KIWA Seisakusho. You can thread them onto chains, etc., to fix parts in place. 2 pieces per pack x 6 packs, for a total of 12 pieces (One pack has been opened, but the pieces are unused and bundled together) Gold color Approximately 6 x 3mm I purchased these, but I'm selling them because I no longer need them. They are unused, but have been stored at home, so please refrain from purchasing if you are concerned.
