GREAT TO USE OR COLLECT. Wille spinner or spinner bait box. These are scarce as hens teeth. Each tray has 14 holders that are springs. There are 3 trays or 3 compartments. The trays can all be removed and use them as one or two or three trays and the handle will be removed and clipped on the middle or on either tray according to how you wish to use it. There are 3 of the springs missing and you can find springs to fit the pegs and make them if you need them. Best I can figure there are 42 pegs and 39 springs so there are a lot of room for to make to fit your needs. The clip rods on the back pull out to remove or add trays as you see fit. Front uses springs to close.
