The perfect companion for on the go: Tools are stored perfectly in our tool case shark and can be used all over the world. The durable shoulder strap evenly distributes the case’s weight for comfortable carrying even with the maximum load capacity for the tool case. The shark is also a good companion for air travel, since the shell is made of airworthy high-density polyethylene and a resilient aluminum rim, which dependably absorbs impacts for optimal tool protection. This tool case maintains its elegant design even after heavy-duty use, as its rugged shell resists dents and dings.
