The Micro Ring Swivel Medium is the perfect choice for any rig where your hook bait is sliding on the hook shank, as it is very neat whilst still giving plenty of freedom of movement. These swivels work perfectly in conjunction with our Hook Beads, and allow more movement than a Rig Ring will do, as well as giving slightly more separation between the bait and hook. They have a dull finish to make them as unobtrusive as possible. Size medium which is equivalent to a size 20.
