If you are looking for an ultra subtle pattern that has proven itself time after time on lock-jawed fish, solid black is the ticket. With a red glowing light stick peeking through the black marabou, this is a pattern that fish won’t ignore!Every Marabou Fire Fly comes with 1 light stick already inserted on the shank of the hook. Once activated, light sticks will last 8-24 hours depending on color, temp, etc.WARNING:Cancer and Reproductive Harm -www.P65Warnings.ca.gov
