Wildlife Research Center Pro-Wick is the scent wick that started it all. These high intensity hunting scent dispensers from Wildlife Research Center are made from special synthetic felt that will not alter the smell of your hunting lure. Simple to use, hunting scent is applied to each Pro-Wick that is then hung on a branch or twig approximately 6 feet off the ground, so the scent is carried right to the deer's nose. May be easily removed at night. Come 4 to a pack in resealable, zip lock bag.
