The set is housed in a blow-molded carrying case with tilted tap holders for easy access and organization, which is a big advantage for staying organized and transporting the tools. Made from alloy steel, the tools are durable, though it should be noted that the taps and dies are untreated and have a full polish chrome finish. This set's weight is quite manageable at 1.3 pounds, making it portable.
