The Shinto Pro Hard Mono Core Single Assist Hooks are the perfect assist hooks for medium to large offshore casting and jigging lures. Thicker gauge, super sharp hooks are dressed with flashy holographic tinsel for extra flare and attraction, and woven onto super strong assist chord that's then attached to super strong rings. The hard mono core within the assist chord adds a lot more strength and abrasion resistance to the assist. The 1/0 - 3/0 sized hooks come in packs of 4 assist hooks. The 5/0 and 9/0 sized hooks come in packs of 2 assist hooks and are much heavier gauge hooks suited for bigger and harder fighting species like big tuna.
