SK1066 Features: * Molded from ultra high molecular weight polyethylene * Resistant to oils, fuels, solvents and acids * Foam not in case * SKB Cases are manufactured of ultra-high molecular weight Polyethylene. This unique material was originally specified by the military for use in weapons cases, due to the fact that it is impervious to solvents, fuels or toxic liquids. It is essentially indestructible, molds easily under heat, and forms an ""impenetrable shield"", thereby protecting whatever it is contains * SKB also utilizes aluminum valance material for its strength and lightweight characteristics on all closures, with a special ""slot"" for a custom fitted Neoprene gasket that assists in sealing out moisture.
