The case color runs through the material so scratches are invisible and the "poly" is impervious to all solvents, oils, fuels and acids. Every case detail is purposefully designed to optimize function. The molded-in configuration of bumpers and ribs are designed to absorb shock and vibration, provide protection for exposed hardware and enhance the structural integrity of the case. Al
