The Flambeau Zerust Max Waterproof Tuff Tainer Bulk Tackle Box combines Zerust with a silicone gasket for the ultimate moisture protection. The box offers anglers an enhanced level of Zerust VCI vapor technology 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 and tasteless vapor.
