USA Made nylon bungee with UVA protection and stainless steel hooks.  Made to hold up in the saltwater environment!

The Rockport Rattler jigs are designed so at there is no lead to muffle the sound. The rattle chamber is flush with the hook, and therefore the hook acts as an amplifier to amplify the sound. Exactly like on a submarine where the sound is amplified and transmitted by a thin wire around the rest of the sub. Therefore the Rockport Rattler is actually louder than a glass rattle by itself or inserted into a soft plastic.
