For the safe transport of any sensitive or valuable material, this waterproof case is made of an HPX ™ resin extremely resistant to shocks but also to temperature variations. Its unique "Press & Pull" locking system is both secure (cannot be accidentally opened) and very easy to handle. Completely sealed to air, water and dust, the case features an O-ring and a Vortex pressurization valve that automatically regulates changes in atmospheric pressure. A rigid rubber-covered handle ensures robustness and comfort during transport.
