Atlas Mike’s Magic Thread We call it Magic because thats 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. Thats all! No knotting required! Simple and effective. Also makes an excellent bait saver. Wrap around bait on hook or lures to hold bait on longer. Works with shrimp, herring, sardine, salmon roe, crayfish, prawn, etc. Every angler needs to have this product in their tackle box!
