One of my Xmas presents, totally unexpected , was a Stanley storage container from Home Depot. It is black and yellow, about 17 X 13 X 2", with 28 removable bins inside covered by a single clear lid with a clasp closure that locks everything into it's bin.

The inside bins fit spools , with other bins for hooks and beads.

Though it was not designed for fly tiers, it is great for this purpose. I've been using it for about a seek and it is saving me a lot of time finding things.
