This lure is primarily used in "light salt game" fishing, targeting fish like rockfish and horse mackerel. The ultra-soft material (U.S.B.) of the worm and its short rib structure create a subtle quivering action even in slight currents, strongly attracting small fish. This is a new, unopened item. It's from 5 years ago, and I'm selling it to organize my fishing gear. Thank you for looking.
