The Atlas Magic Thread With Dispenser gives salmon, steelhead, and trout anglers a quick way to secure spawn sacs and natural bait without tying knots. Make three tight wraps around the stem of a bait sac, pull snug, then repeat with three more wraps to hold everything together. Magic Thread also works as a bait saver for keeping shrimp, herring, sardines, salmon roe, crayfish, prawns, and other natural baits firmly positioned on hooks and lures during casting, drifting, trolling, and other presentations. The convenient dispenser keeps the white elastic thread neat and tangle-free in your tackle box while helping protect it from unwanted odors.
