As it says on the box, this is an organiser. And it has helped me and my tool box look very clean. You have large tools and medium tools, and then you have small tools that are always too much or out of place. This case helped me avoid it. I know where every screw, allen key, drill, bolt, nut, tape, etc. is. The plastic is very strong, the case holds the weight until it fails. The closing and opening tabs are very comfortable. And plus its transparent top so you know what's inside at a glance.
