They are designed to give the hook a more aggressive shape, which will cause it to rotate faster in the fish's mouth, increasing the number of effective hook-ups. They can also be used in Ronnie Rigs at the junction of the swivel and the hook. They are made in five color schemes and three diameters, so you can choose the appropriate color for the type of bottom and the size for the given hook. They shrink at steam temperature without damaging the other components of the rig.
