Boasting the look and feel of live bait, Berkley's Gulp! Alive! Leech is infused with irresistible scent formula for maximum fish attraction. Because these super-realistic Leeches actually "live" in a high-octane Gulp! Alive! solution, they absorb up to 20% more attractant, making them more potent than other lures on the market. Each super-charged Leech disperses its potent scent like a blood trail in the water. When the catching is finished, simply put them back in the bucket to recharge for another day! Made in the USA.
