Wildlife Research Center Pro-Wicks are high intensity hunting scent dispensers 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 5’ off the ground, so the scent is carried right to the animal's nose. May be easily removed at night. Come 4 to a pack in resealable, zip lock bag.
