Plastic tackle trays are nothing more than hardware utility boxes by another name, and they come in as many different configurations as there are bits and bobs to store in them. But the removeable dividers aren't always the most reliable. They come loose and get lost. Or they go unused and take up space because we are loath to throw them away. Since soft plastics, swim baits, hooks, and weights all have unique shapes, the best practice is to know exactly what category of tackle you want to keep in each box and select a tray with as many fixed compartments as possible, keeping those you need to divide to a minimum.
