Found on the hind legs of deer, tarsal glands secrete a musk that deer use to identify other deer and keep tabs on their status in different areas. Buck Tarsal Gland contains a real whole tarsal gland soaked in urine collected from an individual buck. The gland comes with a zip tie that makes hanging it from tree branches or over scrapes even easier. Use all season long as a potent curiosity and infringement attractant.
