Keep fishing tackle clean and organized inside a Flambeau® Ultimate Tuff Tainer® Box. Sporting a watertight O-ring for a complete seal, plus secure locking latches, it's ideal for storing water-sensitive gear. Not only is this versatile tackle box waterproof, but it's also rust-resistant thanks to its added Zerust® technology. Zerust® is a patented VCI polymer that's molded directly into the plastic. It forms a protective layer around clean metal surfaces to stop corrosion in its tracks. Ultimate Tuff Tainer contains 5 fixed compartments with adjustable dividers.
