Pro Model Hook Boxes are a stupendous way to store hooks, beads and eyes securely while preventing them from migrating into each other. The huge advantage to these are the ridges that run down the inside lid to prevent hooks ( or tiny beads) from moving between compartments. They have a living hinge and strong clip down lid closures. We can't stress this enough. They are strong and tight. I have many of them full of heavy beads, cones and eyes. They are so handy. I would be lost without them. I also need to say I use a lot of our utility boxes, but avoid putting beads and eyes in them because they can pop open.easily and also if flipped they will create a terrible mess of jumbled stuff. Again...very good reason to use these when traveling. My lovely wife has a gang of these. She uses them for our kitchen utility drawer and has Oregon-ized everything from rubber bands to paper clips. She loves them for her sewing area too. They are useful in more ways then one. BB MADE IN AMERICA.
