can't get much easier than this. If you work in an office that has those single serve coffee maker things, they usually come in this box (pictured) where there are perforated cutouts for access to the packets. Well they make perfect bins for the workshop for holding nuts, bolts, whatever. Take a piece of masking tape across the front, and you have a label (you'll need a sharpie marker.)
the stack, nicely, can be reinforced with cardboard squares if there is a weight issue, and the opening is perfect for viewing the contents and your hand to reach in.
