We all have storage cases, but these have a feature that solves the issue of parts transferring into other compartments. The Akro-Mils lid has a built in grid system that locks the divider into place and does not allow parts to hang over or transfer, while the clear case allows for visibility of contents. Case comes with a full set of dividers. Overall Size is 14-3/8" x 9-1/2" x 2-1/2". Made in the USA.
