GEWA describes GEWA Pure Polycarbonate Case as follows:
The polycarbonate case guarantees the safety of the instrument in every situation. The shell is made of a polycarbonate sandwich that is injected with polyurethane foam. This makes the case not only very light and stable, but also very temperature resistant. The sturdy main handle and the side handle allow for easy handling. The well-made neoprene padded backpack straps make it very comfortable to carry.
