Atlas Mike's calls it "Magic" because that's what it is! Magic Thread makes tying bait sacs easier and faster: just three turns around the stem of the sac, pull tightly, then three more turns and pull tightly again. No knotting required - simple and effective.
It also makes an excellent bait saver. Wrap it around bait on a hook or lure to hold bait on longer. Works with shrimp, herring, sardine, salmon roe, crayfish, prawn and more.
