The Flambeau Outdoors 550 Medium Spinnerbait Box is specially designed to keep spinnerbaits tangle free and neatly organized. The Medium Spinnerbait Box features [4] compartments that can hold up to [60] spinnerbaits total. Designed with the fisher in mind for quick and organized baiting. The [3] removable spinnerbait rack systems are infused with patented anti-corrision Zerust technology. Zerust-infused plastics emit an odorless, harmless vapor in a contained area to naturally form a protective layer around exposed, clean metal surfaces to prevent oxidation-reduction and stop rust and corrosion.
