Drip some scent or lure on and these wicks, and it sucks it up like a magnet. Just hang them on a branch or twig with the convenient hanger hole and let your scents drift on the wind. Comes packed in a ziploc bag that you can store them in when not in use.
I use these both for deer lure during hunting season and for long distance call lure in trapping. The most practical scent despensers available. Comes in a 4 pack.
