The silver colored bails with a loop are incredibly easy to use. Open the bail prongs, slip the prongs into the drilled hole of your casting and pinch the bail together with your fingers. String your necklace or cord through the bail to hang. The bail is 3/8 inch long with an adjustable 3/8 inch gap.
Come 10 per package.
