2 Plunking Spreaders in each bag. Eliminate frustrating line tangles while plunking. The swivels rotates freely 360 degrees around your wire shaft, allowing your bait to flow correctly behind your spreader. Attach multiple Plunking Spreaders on your leader, to increase your chances of catching. Each spreader has 2 red hard beads on each end of the sliding swivel. Red hard beads are 4mm on the small size and 6mm on the large size plunking spreaders. The remaining material is made out of nickle.
