Made of tough crystal clear poly-carbonate with cam-action latches and Dri-Lock O-ring seal, these cases are designed to be airtight and waterproof. While the non-corrosive pinned hinges provide a strong solid hinge that will last through years of use. The soft rubber lining protects valuables inside. An additional sheet of the rubber lining is included to shield the contents from the sun or to provide privacy to the contents of the case. Perfect for boating, fishing hunting, camping or any situation where secure dry storage is needed.
