schor,
Neat find. Thanks for the tip.
I plan to use one, or more, at the milling machine to organize small items (edge finder, spotting drill, tap drill, countersink, tap, drills, cutters, etc.) that are needed at hand for a project.
All the tools go back into more appropriate storage places when the project is completed, but those trays will be great for keeping things handy and secure for WIP.
Thanks again.
