An organizer, the logical foundation of which is ergonomics. Similar existing organizers had tight corners and vertical walls, so when components were grasped, they were pushed into a corner. The curvature of the Ergo tray matches the human fingertip, while broadly beveled walls avoid tight corners and shift items into a definite spot. 

By hitting it with a scouring pad and re-applying the wax, it will have the same finish as when it was new. If you want to let it ride, the tray will build wear patterns that tell the tale of its use.
