It is designed with a silicone rattle band ring and can be attached to the shoulder of any jig, hook, spinnerbait or spoon to emit sonic rattling vibrations and sound to attract fish to the lure and trigger them to strike. The rattle shell is molded from hard plastic and thumps, ticks, clicks, and clatters when the steel buckshot rattles are jigged to imitate schools of darting bait fish and crawfish on the rocks.
