Check out a Hobby Lobby store, they sell "Craft Mates" locking 14 compartment boxes. I use mine for beads and other small products. Great for hooks also. These are approx. 9 1/4 X 4 1/2 X 1 inches in size. Can't remember the price. I get them when on sale. They also have rounded bottoms like some hook boxes I fasten a cotter pin and brass washer thingie to the one end of the box so I can attach to my vest. I do this to all my fly boxes and it has saved me a lot of money, due to boxes left on a rock or falling out of the vest pocket.
