BALL CHAIN NECKLACE | GOOSEBUMPS - SIZE A - 18"This favorite and absolute staple of Good Art, works great with most pendants, and especially the heavier clips and glasses holders, that sort of thing. The A at roughly 4. 5mm it's a stout chain. As you thought, Good Art does make the Connector piece. Choose your favorite motif. *IF YOU WANT THE CHAIN A LITTLE BIT SHORTER, JUST CUT OFF THE EXTRA BALLS WITH SCISSORS. Rondel included with AA ball chain only.
