These high intensity dispensers are made from special synthetic felt that will not alter the smell of your lure. Simple to use, lure is applied to each Pro-Wick that is then hung on branch or twig approx. 5' off the ground so the scent is carried right to the deer's nose. May be removed at night. This comes 4 to a pack in a resealable, zip lock bag. Lure is not included.
