STURDY MATERIAL - Made with cold-reduced carbon steel sheets and strips (SPCC), the tool box is of great hardness and durability with high load-bearing capacity.        
5-TRAY DESIGN - 4 metal connectors on both sides connect the 5 foldable trays, making it convenient for use with the retractable design. Get easy access to the tools placed in different trays.        
ZINC PHOSPHATE - The surface of the steel tool box is covered by a fine and dense zinc phosphating, providing great rust and corrosion resistance for long-lasting use.      CONVENIENT LONG HANDLES - A pair of metal handles shares the same length with the toolbox. It’s more comfortable to grip and convenient for you to carry around.        
LARGE CAPACITY - With a dimension of 420mm×200mm×200mm, the 18in metal toolbox is of large capacity. (Note- It’s ready to serve out of the box with no installation needed.)
