Self-locking beads for hooks – optimal bait retention. These small self-locking beads attach directly to the hook shank and act as a stop to hold the bait, preventing it from rising too high. They also allow the swivel or ring to slide naturally along the shank for smooth and efficient rigging. Available in 3 colors and sold in packs of 20, they are ideal for all carp anglers looking to optimize their rigs and presentation at the water's edge.
