Atlas Magic Thread With Dispenser makes sac tying fast and straightforward. Just turn three times around the stem of the sac, pull tightly, three more turns around, and pull tightly again. No knotting is required! This thread is simple and effective, and an excellent bait saver. Wrap around bait on the hook or lure to hold the bait on longer. The Atlas Magic Thread With Dispenser works great with baits such as shrimp, herring, sardine, salmon, steelhead roe, crayfish, and minnows. The convenient dispenser keeps thread neat, clean and tangles free. Amount per Roll: 100 ft. Atlas Magic Thread is made in the U.S.A.
