Border Crossing's patented "stick" formula eliminates all of the messy problems of liquid scent products! No spills - tip over a bottle of liquid scent and it's gone No leaks - who hasn't had a stinky bottle of scent leak in a pocket or backpack No mess - no matter how careful you are, layered scent ends up on your fingers (which you smell during lunch) No preservatives - bottled scent requires preservatives. Border Crossing's patented stick formula requires no preservatives so you get 100% pure, unpreserved scent! And, it will not break down in temperatures less than 100 degrees. Won't wash away - A big advantage of wax is that the scent won't wash away in rain or dew like liquid scent. How to use - Apply to training dummy and use for retrieving, or make scent trail by dragging or wiping dummy on ground and hide in cover for the dog to find.
