Pro-Tip: To keep your modular system organized, use the internal metal plate on the lid to store a Klein headlamp. Not only does this keep your light source in a dedicated spot, but it allows you to light up the interior of the box like a desktop lamp when you're searching for small parts or finishing paperwork on the lid's surface.
