It is thin yet strong to hold your bait in place without being noticed by fish. Miracle Thread can be used to hold your bait firmly in place. Excellent to keep bait on plugs or hooks. Use it with herring, sardine, prawn, shrimp, salmon roe, crayfish, and much more! Makes spawn sac tying quick and easy! Just wrap it 8 or 10 times, give it a tug, and break it off. No cutting, no knotting!
