A set of high grade. Magnets can be created with screwdrivers. The steel is of high quality. It is a sturdy box with four locks, you can stand on it, and I am convinced that it can support my weight of 115 kg. A gasket can be found in the space between the covers. Even after standing on the box, the tools and bits that were securely held in their positions did not dislodge and fall out. The purchase has more than satisfied my expectations.
