Approximately 37mm kidney ear wire findings. 21 gauge. Plated brass. Antiqued brass is a warm and inviting metal finish that simulates the look of oxidized brass. After attaching drop, use round-nose pliers to crimp loop closed. This keeps your drop in place. You can also string beads directly onto the wire (a French wire keeper, Bead Bumper or small crimp will hold beads in place when wire is opened/closed).
