Square and deep, the Pelican 1640 Case keeps larger electronics and equipment safe, even in extreme conditions. Outside, there's an ultra-high-impact structural copolymer shell. That means the 1640 case is airtight, watertight, dustproof, crushproof, chemical- and corrosion-resistant and unbreakable. Inside, optional padded divider set and foam set can be configured to hold your most vital valuables.
