The Zerust Max Tuff Tainer line builds on our legacy as the pioneering force and industry leader in anti-corrosion tackle storage innovation to offer anglers an enhanced level of Zerust VCI vapor technology now impregnated directly into the entirety of each box. Flambeau’s exclusive Zerust VCI products consist of a proprietary chemical formulation that releases an invisible, odorless, tasteless, and FDA-safe vapor that diffuses throughout an enclosed Tuff Tainer and settles on all exposed metal surfaces to form a protective molecular layer that inhibits the electrochemical reactions that cause rust and corrosion to form. The result is unmatched rust prevention performance for a minimum of 5 years in the most extreme environments an angler will encounter.
