The Mil-Standard Waterproof Case 6 with Cubed Foam from SKB is made from an injection-molded high-strength polypropylene copolymer resin that is not only impact-resistant, but UV, solvent, corrosion and fungus-resistant. The molded-in hinge provides additional strength. It features a gasket for watertight security up to approximately 3'. This case is typically used to store, and transport delicate equipment such as cameras, electronics, mics and mixers, cables, or musical equipment. The cubed foam interior allows you to pick 'n pluck compartments that can be tailored to custom fit each piece of equipment.
